The ACAS model disciplinary procedure, recommended by NALC, specifies an independent panel of three members of the council. It is a fundamental principle of data protection that personal data is accessed on a "need to know" basis. Where a council has delegated its line management functions, either to a committee or an individual, it should trust those arrangements to deliver or re-consider those arrangements if they fail to do so. The council or its committee has the power to introduce a formal appraisal process and to tailor it to meet their needs. If the current appraisal system isn't working, that's what they should do.
