The route for making a complaint about an MSP will depend on the nature of the complaint. Your complaint will be investigated by the appropriate offices or individuals as detailed in the Guide to making complaints about Members of the Scottish Parliament (MSPs) section.
If you have complained about the conduct of an individual MSP and the complaint is found to be sufficiently serious, it may also be referred on to the Standards, Procedures and Public Appointments Committee (SPPA Committee).
That Committee can recommend to the Parliament sanctions for the MSP (such as suspension of pay or expenses or exclusion from the Parliament for a period of time). If the Parliament votes in favour of those sanctions, they are imposed.
