Its really that simple.
granted it cant happen, servicing the game and all that but I would have all refs do the test, cant do the test, you cant get a match fee.
Even with a change of measurements, instead of 2.6 make it 2.2 for over 50s
There should be some form of test, are teams wanting someone classed as fit enough to do their game, or are they happy with just anybody to do their game...
The onus should be on associations to ensure the people representing them are suitable
And, a level of fitness, when it comes to refereeing, is essential, not, optional.
in the grand scheme of things, i'm certain teams would prefer any referee to potentially not having one at all, even if the ones they did get had passed an annual fitness (and / or LOTG) test
