@ABFoz Many decades ago I was a member of an offroad group in South Australia (ORSA). When we went on long trips, we had a map savvy lawyer, a locksmith and BIG bolt cutters. If it was definitely a public road, gate or not, locked or not, we went along it.
Forget about tribunals ...
We explained the law to the offender about closing off public roads for private purposes (i.e. it was, and is, illegal to do so) and proceeded. Often a convoy of 5-20 vehicles, usually each with a driver and a navigator.
