Sure this is a question in the ATPL Air Law exam, but from Lasors:
The holder of a valid JAR-FCL CPL(A)/IR with JAR-FCL ATPL Theory credit (ie someone who passed the JAR ATPL theory prior to completing the JAR CPL/IR course) will be credited the JAR-FCL ATPL(A) Theoretical knowledge examination for a period of 7 years from the last validity date of the IR(A) entered in the CPL(A).
