Doesn't look like that battery had any bracket holding it in place at all.

I haven't seen the clip. It is no longer available, so I have no idea as to the details, but in NZ for the past few years, we have had each driver sign a declaration that their car conforms to the scrutineering requirements, which thankfully, means you no longer have to throw a sickie on a Friday whilst the scrutineering team tries to get 250 cars through. Instead, getting scrutineered after your third event (or is it after the second?) cuts down the initial workload by at least 50%, leaving scrutineers to prod and poke throughout the meeting.

If any driver appears at a meeting without the battery secured, then they are 100% responsible, but some cars have a retaining lip at the base of the battery - but as I said, I haven't seen the clip.
