268. Revision of determinations of entitlement to supplementary welfare allowance.

An officer of a health board who is duly authorised to determine entitlement to a supplementary welfare allowance may, at any time revise any determination of entitlement to such allowance if it appears to him that the determination was erroneous in the light of new evidence or of new facts which have been brought to his notice since the date on which the determination was given or if it appears to him in a case where an allowance has been payable that there has been any relevant change of circumstances since the determination was given.
