“From the Department’s perspective it enables consistency of approach to evidence gathering and claims handling both in general terms and when compared with the circumstances set out in R(I) 4/03. It would not, in my submission, be desirable to have different ways of handling claims depending on whether there had been a previous award of disablement benefit or not. There is, I submit, also the point that an advantage for claimants in the separate claim scenario is that if successful, a claimant will often benefit from the backdating provisions whereas the effective date rules are not so generous.”
