Former Chelsea doctor Eva Carneiro is to continue her legal case against Chelsea and ex-manager Jose Mourinho.
Carneiro is suing Chelsea for constructive dismissal and breach of contract, and there is a separate but connected legal claim against Mourinho for alleged discrimination.
Ahead of a first hearing on 6 January, Chelsea filed their defence before the midnight deadline on Thursday.
Mourinho was sacked by the Premier League champions on Thursday.
A date for the full tribunal will be set in the new year, and Mourinho and the Chelsea hierarchy will be compelled to give evidence in person.
Carniero's claim includes a request for reinstatement, raising the possibility of a return to Stamford Bridge for her. However, the club will not be forced to take her back.
