With great difficulty. That is one of the challenges of the job, but if there's a legitimate request.... The request has to contain reasonable grounds and it has to identify what the requester thinks has been contravened. I also have the power to self-initiate, which I have done on occasion as well, but once it looks as if there's a legitimate complaint and there are reasonable grounds, then I would go forward. That would not be frivolous and vexatious. There may be a frivolous aspect to it or it may be treated in a frivolous way, but I just look at whether there's a case to be made and whether it should be looked into. But it's not always easy.
