It is somewhat ironic that GMC have achieved such a significant fine by bringing a prosecution under the FP Act, only months before it is revoked. I believe the sentence brings the contravention of fire safety law firmly under the H & S umbrella. The Judge refered to case law brought under H & S legislation in deciding the level of fine.
GMC have consistently brought cases to court when appropriate and I believe other enforcing authorities will have little option but to follow suit when the RRO is enacted. Many, very rich and powerful companies see serially challenging enforcement orders, (that is appealling against an enforcement notce) as little more than an inconveinience. Enforcing authorities had better be ready, the days of 'bluff and persuasion' are, (quite correctly), gone.
