The maternity lady claimed unfair dismissal, Sex Discrimination, pregnancy & discrimination, and burden of proof to the Employment Tribunal (ET)
Employment tribunal held that the maternity lady lost the case, however ET made statements that the company didn't provide proof (terms & conditions, etc) on the burden of proof ground.
Now we can come back to your questions:
1/ Appeal - the lady appealed to Employment Appeal Tribunal (EAT) agaist the ET decision
2/ Cross appeal - the company appeal to the EAT against ET's statement on burden of proof.
3/ The ET's decision was upheld by the EAT, therefore the lady lost and didn't get any compensation.
The case can go to Court of Appeal however if you look at all the facts prior to the claim, the lady can hardly win. She didn't apply for the job, she didn't show any interest to be relocated to Cheltenham and these were recorded in grievance note taking. All hard facts said by her and her union rep.
