My aim with an OPRA would be to see all their communications about denial policies, to see if they have any communications about trying to deny as many people as possible.
When an agency is meant to be a service to people who need help, having ruthless policies with almost no recourse is something that is shameful. If they specifically intend to do this - which could a method to dissuade people from joining and to save money - it would be a scandal IMO.
There is also a possibility that it's specifically targeted against Jews, which could also be discovered with an OPRA request, but I have no idea how likely or unlikely that possibility is.
