It's interesting to note that, overwhelmingly, the view in the professions is that the regulators ALWAYS take the view of the patients, are overwhelmingly unfair, and are OUT TO GET the doctor/nurse/health care professional.
And the view here is it's an old boys network where they will protect the doctor if they possibly can.
As @Signalbox says, my experience is everyone takes their role very seriously and tries to be very fair to both sides.
I absolutely get that WitnessE's posts here make for painful reading. We can all empathise with how awful it must be to be in her(?) shoes. But the panel has to weigh up the complainants evidence against the doctors evidence, and reach a decision which based on the evidence, is proportionate and manages any risks that that doctor poses.
They're not there to uncritically believe either side. If they get it wrong one way, an unsafe doctor continues working. If they get it wrong the other way, someone loses their ability to work which - as @MissLucyEyelesbarrow says - often means they lose their home and their relationship.
These are not decisions anyone involved takes lightly.
