"An Industrial Tribunal shall not consider a complaint ... unless it is presented to the Tribunal before the end of the period of three months beginning when the act complained of was done."
"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 it is just and equitable to do so. "
"An industrial tribunal shall not consider a complaint under this section unless it is presented to the tribunal before the end of the period of 3 months beginning with the effective date of termination or 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 the period of 3 months."

Her mistake as to what her rights were was, as has now been made clear, a mistake of law. It was not a mistake of fact.
