The crushing of the sheath certainly won't be temporary, damage may already have been done.
The compressive forces exerted by tightening a clamp onto most types of armoured or metal sheathed cables (sufficient to provide a low resistance joint for fault or other currents to flow) are liable to cause damage to the conductor insulation and bedding. Such misuse of a clamp is a departure from Regulation 512.1.5
Quoting regulations and best practice does not prove that his temporary fix left the installation in a more dangerous condition than he found it.
Don't get me wrong; I'd love to go to work every day and work only to best practice, but that's not the world we live in and sometimes calls have to be made that are less than ideal. It has already been argued convincingly that this temporary repair was, perhaps, the best that could be done on the day (subsequently it has been pointed out that the clamp was on steel, rather than lead) and I'd like something more that quotes from regs/BPG4 to back up the contention that he left the installation in a more dangerous condition than it had been previously.
