Don't worry "that guy" will get his day in court but there won't be any compensation. This is not just a Jetstar problem and if you want to be outraged at the way disruptive passengers are treated then put those words into a search engine. You might want to look at ICAO's take on the problem, for a problem it is.

LB you really are clueless when it comes to jet RPT operations:
So the safety implications of consuming 2 minutes of final reserve when in a private aircraft in sight of the quiet destination aerodrome in G might be different than for an RPT jet inbound to a busy airport? Crikey. And, in contrast to a MAYDAY from the private aircraft, there could be some response by ATC and others to effectively mitigate the risks of the RPT jet’s fuel state? Struth.
I can just imagine Captain LB blithely disregarding his F/O's concern about landing with the FR not being intact and not declaring MAYDAY fuel. I can also well imagine Captain LB trying to bluster his way through the subsequent Flight Ops and CASA interview explaining why the F/O's use of the Emergency Statement was way over the top as Captain LB knew the aircraft and all its occupants were perfectly safe with 28 minutes of FR in the fuel tank.
