Paragraph 2

Regulations may enable the Occupational Pensions Board to determine, in prescribed circumstances, that an earner, or any group of earners whose employment falls within a particular category or description of contracted-out employments, has been in such employment from a date earlier than would otherwise be the case, not being, in the case of an earner within the scope of the determination, a date earlier than that on which his relevant employment began or a contracting-out certificate was issued in respect of it, whichever is the later.
