The House of Lords has overruled the original employment tribunal, the EAT and the Court of Appeal in this important case. The Lords considered that the main differences between the contracts of full time and part time firefighters are a function of extra hours worked by full timers. In line with the EAT decision in Gibson v Scottish Ambulane Service (not mentioned) it therefore followed that the contracts of both must be treated as equivalent for purposes of the Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 SI 2000/155.
