There is no legislation that requires that the minute reference is recorded in the accounting software for any payment but clearly it is good practice and certainly helps the internal auditor in their work. Don't forget that authority to make a payment is more than a one stage process as for most payments, unless there is delegated authority to the Clerk or someone to make a purchase (usually reserved for routine matters such as stationery), there would have needed to be a resolution authorising the purchase in the first place (and/or delegating authority to someone to do so) which is then followed by a resolution authorising the payment for that purchase.
