"(2) Subject to subsection (3) an [employment tribunal] shall not consider a complaint under this section unless it is presented to the tribunal - (a) before the end of the period of three months beginning with the effective date of termination, or b) within such further period as the tribunal considers reasonable in a case where it is satisfied that it was not reasonably practicable for the complaint to be presented before the end of that period of three months."
"An [employment tribunal] shall not consider a complaint under section 54 unless it is presented to the tribunal before the end of - (a) the period of three months beginning when the act complained of was done;"
"(6) A court or tribunal may nevertheless consider any such complaint, claim or application which is out of time, if, in all the circumstances of the case, it considers that it is just and equitable to do so."
"In the present case it can be accepted that, initially, there was an impediment to the presentation of the complaint, namely the unexplained failure of the letter dated25 March 1992 to reach the Central Office of Industrial Tribunals. The existence, however, of that impediment is not sufficient to satisfy the test of s 67(2) unless the applicant or her advisers, have taken all the steps they should reasonably have taken, in the circumstances, to see that the application was timeously presented. In the present case, that seems to us to depend upon whether the applicant's solicitors took all the steps that reasonably should have been taken to confirm that the application had been duly received."
