The question is, who has the authority to do anything. Has anyone contacted the State Attorney General's office, or the Department of State?
From my point of view, the highway superintendant was effectively removed from performing his duties by a court judge, NOT the town supervisor. The supervisor took this and ran with it. Stating he had the locks changed on the highway building. Big deal. Ask the town supervisor and the town board what if any authority they have in this matter.
When we have judges, govenor's, congressmen, assemblymen, senators, etc. etc. etc., charged with crimes, they still retain office.
