I share your opinion to a certain extent. It would be wise to exclude people who make frivolous complaints. However, we have some reservations about your bill because, among other things, it does not contain specific criteria for identifying a vexatious complainant. Consequently, the Commissioner could perhaps abuse this power.
People from the Office of the Correctional Investigator and some correctional officers have mentioned that more educated inmates are submitting a large number of complaints on behalf of other inmates. The fact that these inmates are considered to be vexatious complainants because they are filing grievances on behalf of others poses a problem.
Are you not concerned that, without specific criteria for identifying vexatious complainants, the Commissioner may deem them to be vexatious complainants? They do make many complaints, and they may be frivolous at times, but they are doing it on behalf of other inmates.
