After months of speculation and two private hearings that failed to result in a settlement, a full public employment tribunal into Eva Carneiro's claims against Chelsea and Jose Mourinho, after the club's former doctor was demoted from first-team duties and quit in September, will begin in Croydon on Monday.
Here, ESPN FC takes a look at the main questions surrounding the case.
What is Carneiro claiming?
She is pursuing claims of constructive dismissal against Chelsea, as well as victimisation and discrimination against Mourinho personally. In legal terms, "constructive dismissal" is defined as a situation in which a person is forced to leave their job against their will because of their employer's conduct, such as an unjustified demotion.
Carneiro is alleging that her demotion from first-team duties, in the wake of Mourinho branding her and head physio Jon Fearn "impulsive and naive" for entering the Stamford Bridge pitch to treat Eden Hazard in the closing stages of Chelsea's 2-2 draw with Swansea City in August 2015, meets this definition.
She is also alleging discrimination and victimisation by Mourinho. To prove the claim of discrimination, Carneiro must show the tribunal evidence that she was treated unfairly as a direct result of her sex, a protected characteristic in the Equality Act 2010.
"Victimisation" is defined in UK employment law as when a person is treated badly because they complain about discrimination, or help someone else who has been the victim of discrimination.
What is she looking for?
Prior to the second private hearing between the parties in March, Carneiro's barrister Mary O'Rourke QC publicly confirmed for the first time that her client is seeking substantial damages for her treatment, as well as a public apology from Mourinho himself.
Sources have told ESPN FC that Chelsea have always regarded a full public tribunal -- and the embarrassing revelations that such a procedure could bring -- as a last resort. But above all, Carneiro says she is looking to restore her professional reputation, which she argues has been severely damaged by this acrimonious episode.
What will happen at the tribunal?
Evidence will be presented to the tribunal panel, which consists of three members: a lawyer who is chair, and takes the title of "employment judge," and two lay members, one of whom has experience as an employer and another whom has experience as an employee. Tribunal hearings are less formal than those in a court, but evidence is still taken under oath.
The initial burden of proof rests on Carneiro. If her representatives can provide sufficient evidence to the panel that she has grounds for constructive dismissal and that sex discrimination and victimisation could have occurred, it then falls to Chelsea and Mourinho to provide evidence that refutes this.
Carneiro's legal team could decide to call Mourinho and Chelsea players as witnesses, as well as demand access to text messages and emails that may be relevant to the case. These would then be made public.
After considering all the evidence supplied, the panel will make its judgment.
Will Carneiro and Mourinho be there?
Carneiro attended both private hearings in January and March, flanked by her legal team and her husband, the polar explorer Jason De Carteret, so it would be a surprise if she were not present in Croydon when the tribunal begins Monday.
Mourinho did not attend either hearing and was not personally represented in March, which suggests that Chelsea have agreed to indemnify him for any costs and potential damages arising from the tribunal.
He may have agreed to provide a statement and appear as a witness. If not, the new Manchester United manager could still be compelled to give evidence in person if ordered to do so by the tribunal, but he would not have to provide a statement beforehand and the party who requested the order would likely have to pay his travel expenses.
Will this affect Mourinho's start to life as Manchester United manager?
Not in any tangible sense. The tribunal is expected to go on for no longer than 10 days and finish by June 24 at the latest, well before the end of Euro 2016 and almost a month prior to the start of United's preseason tour of China. At worst, Mourinho will be required to pay substantial damages to Carneiro if her claims of discrimination and victimisation are upheld.
Might Carneiro yet be reinstated at Chelsea?
Several reports on her decision to initiate legal proceedings in November claimed that Carneiro was also seeking reinstatement to her former role, and Chelsea have not yet hired a direct replacement first-team doctor within their extensive fitness and medical staff. But Carneiro accepted a new job in March, as a sports and medicine exercise consultant at a specialist medical clinic in her native Gibraltar, so it is unlikely she would even want to return now.
