I'm in the process of assisting client with claim for backdated HB/CTB claim.

The LA have have decided that client does not meet the "good cause" criteria. They refer to legislation they have used as Housing & Council Tax (General) Regulations 72(15)& 62(16)

I am unable to locate these regs online to check they are using the correct regs and would be grateful if any one could provide a link to these as well as details of HB reg 83(12, HB regs: reg64(13).

Those are the "old" Regulations and no longer in force.

Reg 83(12) of the current Hb regs is copied below. The CTB Reg is much the same.

(12) Where the claimant makes a claim in respect of a past period (a "claim for backdating") and, from a day in that period up to the date of the claim for backdating, he had continuous good cause for his failure to make a claim, his claim in respect of that period shall be treated as made on—
(a) the first day from which he had continuous good cause; or
(b) the day 52 weeks before the date of the claim for backdating, whichever fell later.

Not overly helpful so the link to the "Good Cause"part of the Hb manual is below.

Thanks for your help on this matter and as you say the regs have now changed to 83(12)

The classic definition of good cause is found in R(S) 2/63, at paragraph 11.
