Initial MP Type Rating: Pre-Requisite Training

Hi,
JAR FCL 1.250 states that a valid MEIR is required as a pre-requisite prior to commencing an initial MP Type Rating course. However, Lasors 2005 states that a valid MEIR within the last five years is all that is required and from recent posts I believe this is the current requirement of the CAA.
Does any Irish licence holder know the position adopted by the IAA in this regard?
Regards
Willby
