Mental capacity – Power of attorney. Where the signature of B, aged 84, on lasting powers of attorney had been witnessed by one of the attorneys, and where her capacity had subsequently deteriorated, the requirements of reg 9(8)(b) of the Lasting Power of Attorney, Enduring Power of Attorney and Public Guardian Regulations 2007, SI 2007/1253, had not been met. Accordingly, the Court of Protection ruled that the LPAs conferred no authority and, accordingly, the Public Guardian was directed to cancel their registration.
