In Byrnell v British Telecommunications plc, the EAT holds that in a case where the applicant sought to claim a repudiatory breach of a compromise agreement so as to release himself from any obligations under it, the tribunal was correct to conclude that it had no jurisdiction to entertain claims in relation to the compromise agreement, except to satisfy itself that the compromise agreement met the requirements of s.203 of the ERA 1996 in terms of form and legal advice.
