I think JMM might mean a bogus admin fee that some schemes think they can add to the the cost of enforcing by-laws.
This would be highly dubious even if the OC won their case. If they lost, it would be ridiculous to still impose it. These admin fees are often intended to deter owners from fighting notices to comply at NCAT. I have a feeling they may be illegal as even NCAT will not award costs except in special circumstances.
JMM should ask for a formal letter withdrawing the charge, and propose a motion at the next committee meeting that they investigate the legality or otherwise of such charges.
