Yes, if the date of termination is in dispute, held the EAT in Basra v BJSS Limited.

Pre-termination discussions between employer and employee are protected under section 111A Employment Rights Act 1996 and cannot therefore usually be referred to by either party in an unfair dismissal claim, unless there has been “improper behaviour”. In Basra, however, the EAT held that there is an exception to this rule if the date of termination is in dispute.

The Claimant wrote an email to the Respondent in response to a without prejudice offer letter it had sent saying “today will be the last day at BJSS”. The Claimant then stopped attending work, and later brought a claim for unfair dismissal. BJSS argued the Claimant’s employment had ended by mutual termination and, in the alternative, the email was a resignation. The Claimant denied resigning and said he had been dismissed by BJSS at a later date. The tribunal, following Faithorn Farrell Timms LLP v Bailey, noted that s111A protection cannot be waived (unlike without prejudice negotiations) and excluded BJSS’s offer letter as protected under s111A ERA.

The EAT held that as the protection under s111A only applies to pre-termination negotiations, “the chronological line between what is, and what is not, admissible therefore lies on the point at which the contract is terminated”. The EAT went on to say that “where there is a dispute as to whether or not the contract was terminated on a particular date, the tribunal would not be in a position to say what evidence should be excluded until that dispute is determined”. Thus the tribunal needs to determine the termination date before applying s111A

In King v The Sash Window Workshop Ltd and anor, the European Court of Justice has held that the means of enforcing the right to paid holiday under the Working Time Regulations 1998 SI 1998/1833 is incompatible with the EU Working Time Directive (No.2003/88). On the EAT’s interpretation of Regs 13 and 16, where an employer grants only unpaid leave to a worker, the worker would be obliged to take leave without pay and then bring an action to claim payment for it. This result is incompatible with the right to paid annual leave under Article 7 read with the right to an effective remedy under Article 47 of the EU Charter of Fundamental Rights. The ECJ also held that, where the employer refuses to pay for annual leave, the worker’s holiday rights carry over until the termination of employment.

K worked for SWW Ltd as a self-employed commission-only salesman from June 1999. He was offered an employment contract in 2008, which included the right to paid annual leave. However, he elected to remain self-employed (under a contract that was silent on the issue). While K did take some holiday throughout his years of service, he was never paid for this. When SWW Ltd terminated his engagement in October 2012, K successfully claimed holiday pay before an employment tribunal, which accepted that he was a ‘worker’ for the purposes of the Working Time Regulations 1998. Among other things, the tribunal awarded him pay in lieu of annual leave accrued but not taken during previous years, also claimed as a series of deductions. The EAT allowed SWW Ltd’s appeal on this issue, holding that the tribunal had failed to make findings of fact to support its conclusion that K was prevented from taking his annual leave for reasons beyond his control. There was therefore no basis for departing from the usual position under Reg 13 that entitlement to leave expires at the end of the relevant leave year. K appealed to the Court of Appeal, which made a reference to the ECJ, querying whether Reg 13 is consistent with the right to paid annual leave under Article 7 of the Working Time Directive, given that (on the logic of the EAT’s analysis) the worker would first have to take unpaid leave before testing his or her entitlement to pay. It also sought clarification of the extent to which untaken paid leave can be carried over, for the purpose of claiming a payment in lieu of untaken holiday upon termination of employment under Article 7(2) of the Directive.

Advocate General Tanchev gave the opinion that employers are bound to provide an ‘adequate facility’ for workers to exercise the right to paid annual leave under Article 7, such as in the form of specific contractual terms or the establishment of a legally enforceable administrative procedure. Where no such adequate facility has been made available, any reference and carry-over periods that would otherwise fall within a Member State’s discretion must necessarily be disapplied. In such a case, the worker would be entitled on termination of employment to payment in lieu of annual leave untaken up until the date on which an adequate facility was made available.

a worker must be entitled to benefit from the remuneration to which he or she is entitled when taking his or her annual leave

The ECJ has now given its judgment and has gone further than the Advocate General. It noted that it was clear from its case law that a worker must be entitled to benefit from the remuneration to which he or she is entitled when taking his or her annual leave. Thus, a worker who is faced with uncertainty as to the level of remuneration to which he or she is entitled during the leave period will not be able to benefit fully from that leave as a period of relaxation and leisure, and is likely to be dissuaded from taking leave in the first place. When seen in that light, the right to paid annual leave cannot, therefore, depend on a factual assessment of the worker’s financial situation when he or she takes leave.

Turning to the Working Time Regulations, the ECJ observed that they implement the right to paid annual leave by way of two separate rights: a right to a period of annual leave under Reg 13 and a right to be paid in respect of that leave under Reg 16. Likewise, Reg 30 provides for two separate judicial remedies. The ECJ noted that, on the EAT’s interpretation of Regs 13, 16 and 30, a worker can claim breach of Reg 13 only to the extent that his or her employer did not permit him or her to take any period of leave, whether paid or not; and can claim payment under Reg 16 only for leave actually taken. This has the effect that, where the employer grants only unpaid leave, a worker is obliged to take leave without pay in the first place and then to bring an action to claim payment for it. The ECJ held that this result was incompatible with Article 7 of the Directive when read with Article 47 of the EU Charter. In K’s particular circumstances, he would be unable to claim after the termination of employment in respect of paid leave due but not taken, which would deprive him of an effective remedy.

As to the accumulation of the right to paid annual leave, the ECJ noted that, in the case of a worker who is prevented from taking paid annual leave due to sickness, case law has permitted national law to limit the worker’s right to carry over that leave to 15 months. That case law took into account not only the protection of workers but also the protection of employers, who might otherwise be faced with the risk that a worker will accumulate periods of absence of too great a length. In contrast, in the present case, there was no requirement to protect the employer’s interests – on the facts, SWW Ltd was not faced with organisational difficulties and indeed was able to benefit from K not taking any paid annual leave. It was irrelevant that SWW Ltd considered, wrongly, that K was not entitled to paid annual leave – it is up to the employer to inform itself of its obligations in this regard and an employer that does not allow a worker to exercise his or her right to paid annual leave must bear the consequences. The ECJ therefore concluded that the Directive requires a worker to be able to carry over and accumulate paid annual leave rights until the termination of his or her employment where those rights have not been exercised over several consecutive reference periods because the employer refused to remunerate that leave.

This case has significant implications for the right to holiday pay in the UK. It suggests that workers who are wrongly classified as self-employed contractors may be able to claim back pay in respect of unpaid annual leave going back many years when their ‘worker’ status is established. It also suggests that the Deduction from Wages (Limitation) Regulations 2014 SI 2014/3322, which limit back pay claims to two years, are incompatible with EU law.

 

ECJ Judgement – Allowance in lieu of annual leave paid on termination of the employment relationship

 

In Chief Constable of Norfolk v Coffey the EAT has upheld the decision of an employment tribunal that a police officer, who was turned down for a transfer to the Norfolk Constabulary because her hearing loss was marginally below the medical standard for police recruitment, had suffered direct discrimination because of a perceived disability. The Constabulary’s reason for refusing the transfer was the concern that the claimant would end up on restricted duties. This indicated that it perceived her to have a progressive condition which, by virtue of paragraph 8 of Schedule 1 to the Equality Act 2010, met the statutory definition of disability.

In 2011 C applied to the Wiltshire Constabulary to become a police constable. She attended a medical, at which it was discovered that she suffers from bilateral mild sensori-neural hearing loss with tinnitus. Although C’s hearing loss was marginally outside the range set down by the Home Office for police recruitment, the Wiltshire Constabulary arranged a practical functionality test which C duly passed before going on to work on front-line duties. In 2013 C applied to transfer to the Norfolk Constabulary. C attended a pre-employment health assessment, where the medical adviser noted that her hearing was ‘just outside the standards for recruitment strictly speaking’ but that she had undertaken an operational policing role with the Wiltshire Constabulary without any undue problems. He recommended that C undergo an ‘at work’ test, but this recommendation was not carried through by the Assistant Chief Inspector (ACI) who dealt with the application. Instead, the ACI declined C’s request to transfer on the basis that her hearing was below the acceptable and recognised standard, and that it would not be appropriate to step outside that standard given the risk of increasing the pool of officers on restricted duties.

C brought an employment tribunal claim for direct discrimination. It was not alleged that she actually had a disability; her case was that her hearing loss did not have, and was not likely to have, a substantial adverse effect on her ability to carry out day-to-day activities, including working activities. Instead, it was argued that she had been treated less favourably because she was perceived to have a disability, in the form of a progressive condition that could well develop to the point of having a substantial impact on her ability to carry out day-to-day activities. The tribunal considered that the only way to read the ACI’s comments about the risk of C ending up on restricted duties was that she perceived that C had a potential or actual disability which could lead to the Constabulary having to make adjustments to C’s role as a front-line police officer. Since this perception was the reason for refusing C’s transfer, the tribunal upheld the discrimination claim.

On appeal to the EAT, it was argued that the tribunal had erred both in respect of its finding that the ACI perceived C to be disabled and its finding that C had been treated less favourably because of that perception. On the former point, the EAT stressed that the question of whether a putative discriminator A perceives B to be disabled will not depend on whether A perceives B to be disabled as a matter of law. It will depend on whether A perceives B to have an impairment with the features which are set out in the legislation. Paragraph 8 of Schedule 1 to the EqA makes special provision in respect of progressive conditions. Where a person has a progressive condition that results in an impairment having an effect on his or her ability to carry out day-to-day activities, but the effect is not a substantial adverse effect, it will still be treated as such if it is likely that the condition will result in a substantial adverse effect in future. Although the ACI protested that she did not consider C disabled with the meaning of the EqA, her knowledge of the law was incomplete and did not include Paragraph 8 of Schedule 1. The reference to the risk of C being on restricted duties could only be read as the ACI perceiving that C had a progressive condition which could worsen. Thus, the tribunal had been entitled to find that she perceived her to be disabled.

Turning to whether the tribunal had been correct to find that there had been direct discrimination, the EAT accepted that a genuine difference in abilities will be a material difference between claimant and comparator. However, it saw no warrant for an employer’s flawed belief in a lack of ability to be a material difference. The tribunal was entitled to conclude that a person with the same abilities as C, whose condition the employer did not perceive to be likely to deteriorate so that he or she would require restricted duties, would not have been treated as C was. C had performed an active policing role in Wiltshire; she had been accepted at the interview stage; her rejection followed when the ACI ignored advice to rely on a practical assessment of C because, as the tribunal put it, she believed the C would become a liability to the force. The tribunal did not err in law in concluding that she had been subjected to direct discrimination.

Can a Respondent employer rely on parts of a ‘without prejudice discussion’, or protected conversation, whilst at the same time using the rules as a shield?

No, held the EAT in Graham v Agilitas IT Solutions Ltd.

The Claimant was facing termination of employment. During talks which the Respondent characterised as being without prejudice and/or protected under s111A of the Employment Rights Act 1996, the Claimant made comments which the Respondent subsequently used to form the basis of disciplinary action. The Claimant alleged improper conduct/unambiguous impropriety by the Respondent in the form of bullying and threatening behaviours in the same meeting.

The EAT held that the Respondent could not waive privilege on parts of the meeting and rely on privilege in relation to other parts to shield its conduct.

The Claimant was entitled to have the employment tribunal examine the improper conduct. The case has been remitted.

Employment tribunal was wrong to reject the wrongful constructive dismissal claim

In Rawlinson v Brightside Group Ltd, the EAT has held that an employment tribunal was wrong to reject the wrongful constructive dismissal claim of an employee who resigned when falsely told that he was to be dismissed due to a work reorganisation (the real reason was his performance). The tribunal erred both in its failure to find that the employer had acted in breach of the implied term of trust and confidence and in its characterisation of the employee’s complaint as relating to the manner of his dismissal. By deciding to give him a reason for the termination of his employment, the employer had assumed an obligation not to mislead, an obligation it then breached. The complaint did not relate to the dismissal but to the falsehood told with a view to keeping the relationship alive for the notice period.

R was employed as an in-house legal counsel by BG Ltd, a firm of insurance brokers. A few months into his employment, the company decided to dismiss R due to concerns about his performance, despite never having raised these with him. To ‘soften the blow’, R was simply told that BG Ltd had decided to outsource legal services. It wanted him to work through his three-month notice period to ensure a smooth handover of work. However, R resigned with immediate effect on the basis that that any outsourcing exercise would constitute a ‘relevant transfer’ under TUPE and the company was therefore breaching its statutory obligations. R subsequently brought employment tribunal claims for, among other things, breach of the duty to inform and consult under TUPE and wrongful constructive dismissal (based upon a fundamental breach of the implied term of trust and confidence).

The tribunal rejected R’s TUPE claims, finding that there was no relevant transfer. As for the contract-based claim, the tribunal found that the company’s failure to forewarn R of any performance concerns and the potential for dismissal did not amount to a breach of the implied term of trust and confidence. Although R genuinely, and with some cause, believed that he was unfairly treated, BG Ltd had no obligation to provide the information to him. The tribunal considered that R’s complaint was really about the manner of his dismissal. This meant that it would be precluded by the House of Lords’ decision in Johnson v Unisys Ltd 2001 ICR 480, where it was held that common law damages for breach of contract cannot be awarded in respect of unfair treatment connected to a dismissal. R appealed.

The EAT agreed with R that in all but the most unusual cases, the implied term of trust and confidence must import an obligation not to deliberately mislead. This does not mean an employer is necessarily placed under some broader obligation to volunteer information, such as a reason for dismissal. Nevertheless, where a choice has been made to do so, the implied term requires that it is done in good faith. Even allowing that there may be particular cases in which the operation of the implied term would permit some element of deceit – the ‘white lie that serves some more benign purpose’ – the EAT could not see how that was so here. The tribunal had therefore erred in failing to find that the implied term had been breached.

The tribunal had further erred in failing to see that R’s complaint did not relate to the dismissal, but to the falsehood told to him with a view to keeping the relationship alive for the notice period. It therefore did not fall within the ‘Johnson exclusion zone’. As the House of Lords recognised in Eastwood and anor v Magnox Electric plc (Brief 762), if an employee suffers loss as a result of an employer’s breach of the implied term in the steps leading to a dismissal, he or she has a common law cause of action that precedes, and is independent of, the subsequent termination of employment. R’s response to the communication of an untrue reason for his dismissal was to walk out, giving rise to a loss of earnings over the notice period. The EAT therefore allowed the appeal and substituted a finding that R’s wrongful dismissal claim should succeed.

In Ayodele v Citylink Ltd and anor, the Court of Appeal has held that the burden of showing a prima facie case of discrimination under S.136 of the Equality Act 2010 remains on the claimant. This provision made no substantive change to the law when it came into force in October 2010 and Mrs Justice Elisabeth Laing was wrong to hold otherwise in the EAT in Efobi v Royal Mail Group Ltd.

A, a black man originally from Nigeria, brought a number of claims against his former employer, C Ltd, following the termination of his employment, including claims of race discrimination. The tribunal dismissed his discrimination claims on the basis that A had not established prima facie evidence of less favourable treatment and therefore the burden of proof had not shifted to the respondent. A’s appeal to the EAT was dismissed. Before the Court of Appeal, A raised a new ground of appeal. He submitted that there was a fundamental error in the approach taken by the employment tribunal as to the proper application of the burden of proof under S.136 EqA. He relied on Elisabeth Laing J’s decision in the EAT in Efobi v Royal Mail Group Ltd (Brief 1078), to the effect that the wording of S.136 EqA does not impose a burden of proof on a claimant at all. Instead, it requires the tribunal to consider all the evidence, from all sources, at the end of the hearing, so as to decide whether or not there are ‘facts’ from which it can conclude that discrimination occurred and, if so, it must so find unless the respondent can discharge the burden on it. A pointed to the fact that in his case the tribunal had directed itself that there was a burden of proof on him at the first stage of the enquiry and therefore it fell into error.

The Court of Appeal dismissed the appeal. It noted that the wording of S.136 EqA is different from the wording of the equivalent predecessor provisions, in that there is no longer any express reference to the claimant being required to prove facts. It rejected A’s suggestion that there was an analogy to be drawn with the assessment of fairness of a dismissal in an unfair dismissal case, where there is no burden on either party. In that context, the tribunal is required to make an assessment in which it is not apt to refer to the burden being on either party. However, in a discrimination case, before a tribunal can start making an assessment, the claimant has got to start the case, otherwise there is nothing for the respondent to address and nothing for the tribunal to assess.

The Court of Appeal could see no reason why a respondent should have to discharge the burden of proof unless and until the claimant has shown a prima facie case of discrimination that needs to be answered. Accordingly, it held that there is nothing unfair about requiring a claimant to bear the burden of proof at the first stage.

The Court also observed there was no reason to suppose that Parliament enacted S.136 to remove the burden of proof from a claimant. Furthermore, the EU Burden of Proof Directive (No.97/80), which S.136 gives effect in domestic law, does not require there to be no burden on a claimant at the first stage, and the legal community has proceeded for the last seven years on the assumption that no change of substance was made by S.136. The change in wording from the predecessor provisions simply made clear that what should be considered at the first stage is all the evidence, and not only the evidence adduced by the claimant: it should be regarded as no more than legislative ‘tidying up’. The Court concluded that previous decisions of the Court of Appeal, such as Igen Ltd and ors v Wong and other cases (Brief 777), as approved by the Supreme Court in Hewage v Grampian Health Board (Brief 958), remain good law and should continue to be followed by the courts and tribunals. It therefore held that the interpretation of S.136 by Elisabeth Laing J in the EAT in Efobi was wrong and should not be followed.

EA Dismisses Uber Appeal against Employment Tribunal Decision

In Uber BV and ors v Aslam and ors, the EAT has dismissed Uber’s appeal against the employment tribunal’s decision that its drivers are ‘workers’ within the meaning of S.230(3)(b) of the Employment Rights Act 1996 and the equivalent definitions in the National Minimum Wage Act 1998 (NMWA) and the Working Time Regulations 1998 SI 1998/1833 (WTR). It held that the tribunal was entitled to reject Uber’s characterisation of its business as a technology platform rather than a provider of transport services, and to look beyond the contractual documentation describing drivers as self-employed contractors offering their services to passengers via the Uber app. The EAT also approved the tribunal’s finding that the drivers could be considered to be working for the purpose of the NMWA and the WTR at any time when they were logged into the Uber app, within the territory in which they were authorised to work, and able and willing to accept assignments.

The Uber business relies on a smartphone app through which customers can order and track a taxi and pay the fare. Uber treats drivers as self-employed and there is complex contractual documentation between it, the drivers and the passengers. Uber seeks to present itself as a technology platform facilitating the provision of taxi services, not as the provider of the taxi service itself. It holds itself out as acting as agent for the drivers, and its agreement with passengers states that the contract for the taxi service is between the driver and the passenger. Under the contract between Uber and the driver, the driver is not required to make any commitment to work. However, when a driver signs into the app, this usually signals that they are coming ‘on-duty’ and are therefore able to accept bookings. As for day-to-day work, prospective passengers book trips through the app. Upon receipt of a passenger request, the app locates an available driver (i.e. one who is logged in). The selected driver has ten seconds to accept the booking through the app, failing which Uber assumes that the driver is unavailable and locates another. If a driver fails to accept bookings, warning messages are generated which can lead to the driver’s access to the app being suspended or blocked (which prevents the driver working).

A number of Uber drivers brought employment tribunal claims of unlawful deductions from wages, relying on failure to pay the national minimum wage, and failure to provide paid annual leave. Two of the drivers were selected as test claimants and the employment tribunal considered, as a preliminary issue, whether the drivers were ‘workers’ for the purpose of S.230(3)(b) ERA. The tribunal found that they were. It rejected Uber’s case that the drivers were self-employed, and that it merely provided the technology platform that allows drivers to find and agree work with individual passengers. In the tribunal’s view, this characterisation of Uber’s business model and the contractual documentation created to support it did not accord with the reality of the working arrangements, which was that Uber relies on a pool of workers to provide a private hire vehicle service. As for what periods would count as ‘working time’ for the purposes of the WTR and the NMWA, the tribunal concluded that the drivers should be treated as working whenever they are in the territory in which they are authorised to drive, have turned on the app, and are ready and willing to accept fares. Uber appealed to the EAT.

The EAT dismissed the appeal. Her Honour Judge Eady QC, sitting alone, held that, following the Supreme Court’s decision in Autoclenz Ltd v Belcher and ors (Brief 934), the tribunal was entitled to find that the contractual documentation did not reflect the reality and thus that it was entitled to disregard the terms and labels used in the written agreements. The tribunal was required to determine the true agreement between the parties and, in so doing, it was important for it to have regard to the reality of the obligations and the situation. The tribunal was therefore bound to focus on the statutory language, rather than the labels used by the parties, and reach a fact-sensitive decision.

HHJ Eady QC noted that the key question was: when the drivers are working, who are they working for?

Uber submitted that the tribunal had failed to understand its argument that an agency arrangement, whereby it acted as agent in relation to contracts between drivers and passengers, was common in the private hire industry. However, in HHJ Eady QC’s view, the tribunal was not denying the possibility of individual drivers operating as separate businesses and, as such, entering into direct contracts with passengers, it was merely saying that this was not what it found to be the true position. It was entitled to take into account, among other things, the scale of the business, rejecting the notion of Uber as ‘a mosaic of 30,000 small businesses linked by a common platform’. The tribunal was also entitled to rely on its finding that drivers were integrated into Uber’s business, and were marketed as such. HHJ Eady QC also rejected Uber’s argument that the tribunal erred by taking into account features of the relationship that resulted from regulatory requirements as indicia of an employment relationship – it was not obliged to disregard factors simply because they might be seen as arising from the relevant regulatory regime.

As for the tribunal’s conclusion with regard to working time, Uber argued that the tribunal failed properly to take into account that, even while signed into the app, drivers were at liberty to take on or refuse work as they chose, or to cancel trips already confirmed, and could even work for others, including direct competitors of Uber. It therefore submitted that, in those circumstances, they were not at Uber’s disposal or working for Uber. HHJ Eady QC conceded that this aspect of the appeal had caused her some trouble. However, she was satisfied that the tribunal had grappled with this issue and reached a permissible conclusion. The tribunal had made a finding that drivers were expected to accept at least 80% of trip requests when signed in, and that being ‘on duty’ meant being ‘willing and able to accept trip requests’. Even if the evidence allowed that drivers were not obliged to accept all trips, the very high percentage of acceptances required justified the tribunal’s conclusion that, once in the territory with the app switched on, drivers were available to Uber and at its disposal.

Does the EU Working Time Directive allow for weekly rest for a worker of 24 hours to be given at any point in a 14-day period?

Yes, held the European Court of Justice in Maio Marques da Rosa v Varzim Sol. The case arose from a redundant casino worker in Portugal, who claimed his employer had not given him a weekly rest period of 24 hours at the appropriate time, and it should have been given at the latest after six consecutive working days. The casino operated 12 hours a day, 364 days of the year.

The CJEU held that there was no requirement for weekly rest to be provided after six consecutive days of work, it can be provided within each 7-day period. Therefore, the Directive allows a working pattern with a rest day at the start of one 7-day period and another rest day at the end of the following 7-day period, so working 12 consecutive days is permissible under the Working Time Directive.

 

Is it a whistleblowing dismissal if the person who made the decision to dismiss was ignorant of the protected disclosure, and was deliberately misled by the employee’s line manager to believe the reason was poor performance?

No, held the Court of Appeal in its judgment in Royal Mail Ltd v Jhuti. Link to Judgement

Ms Jhuti was an employee at Royal Mail who made a protected disclosure to her line manager. During a dismissal process, the line manager, motivated by the protected disclosure, deliberately misled the investigating manager so that she dismissed Ms Jhuti for poor performance. The EAT held that both the reason and motivation of the decision maker and the line manager had to be taken into account, and could be attributed to their employer.

In reversing the EAT’s decision, the Court of Appeal held that in determining the “reason for the dismissal”, the tribunal is only obliged to consider the mental processes of the person(s) authorised to, and who did, take the decision to dismiss (being the mind of the employer). Underhill LJ raised some doubt about whether, in cases of manipulation, the position would be different if the CEO deliberately manipulated the dismissal decision.

Underhill LJ stressed that unfair dismissal cases require unfairness by the employer. Unfair conduct by individual managers or colleagues is immaterial unless it can properly be attributed to the employer.

In principle, Ms Jhuti is not precluded from recovering compensation for dismissal consequent on unlawful detriment but this is for the employment tribunal to decide.

 

Does an embassy employee have diplomatic immunity in respect of employment claims from his domestic staff?

No, held the Supreme Court in Reyes v Al-Malki. Link to Judgement

Mr and Mrs Al-Malki employed Ms Reyes as a member of domestic staff at their London residence. Mr Al-Malki was a diplomat of the Saudi Arabian embassy in London.

In circumstances very similar to yesterday’s case of Benkharbouche v Secretary of State for Foreign & Commonwealth Affairs & Anor, Ms Reyes began employment tribunal proceedings and alleged that Mr and Mrs Al-Malki mistreated her during her employment and that she is a victim of human trafficking. Those allegations have yet to be determined and the issue for the Supreme Court was whether the tribunal has jurisdiction to hear the claims within the exception to the rule of diplomatic immunity, contained in Article 31(1)(c) of the Vienna Convention on Diplomatic Relations 1961.

The Supreme Court unanimously held that Mr Al-Malki would not be entitled to diplomatic immunity in relation to a claim of human trafficking brought by Ms Reyes because her employment (to carry out domestic tasks) and alleged treatment would not constitute acts performed in the course of the diplomat’s official functions.
