An authorised officer of the appropriate enforcement authority may issue to a person a fixed penalty notice in relation to a relevant offence.

In this Part, “fixed penalty notice” means a notice offering the person to whom it is issued the opportunity to discharge liability to conviction for the relevant offence in relation to which the notice is issued by paying to the appropriate enforcement authority a specified sum of money.

The sum of money is to be treated as paid only if it is paid by such method of payment as the appropriate enforcement authority determines to be acceptable.

An authorised officer may issue a fixed penalty notice to a person in relation to a relevant offence only if the officer is satisfied to the specified standard that the person has committed the offence.

A sum specified for the purposes of subsection (2) must not exceed level 4 on the standard scale.

In this section, “standard scale” has the meaning given in section 225(1) of the Criminal Procedure (Scotland) Act 1995.
