1.If the game is abandoned, it has to be played again.
2.If a team refuses to accept an official (before or during the game), then the FA decide.
I fear that this ref may have botched it by officially abandoning the game instead of passing it on to the FA to decide the outcome.
What usually happens in such cases is that a member of the crowd (qualified ref) volunteers. It is highly unlikely that this official will NOT be a supporter of one of the teams, usually the home side. I recall an article in the NLP where a 17 year old lad came on as substitute assistant referee at Stafford - minors are permitted to do this provided that they are qualified referees as they are under adult supervision (the match referee). This has happened many times in the past especially in the days before fourth officials. How many spectators at any game can really classify themselves as neutral?
In today's instance, it is highly unlikely that a Colwyn Bay fan or official would have made themselves available. To a degree,I can see their objection to the replacement being an actual official of their opponents. I also question if their objection would have been the same had they been winning. However there is little credibility to Frank Sinclair's objection, as a replacement referee would have very little influence as the Referee has final decision with any decisions and would over-rule any that he is not in agreement with, including the offside rule. Unless the FA Trophy competition rules say stipulate otherwise, there is no reason that the Referee taking over could not not have finished the game minus one of the assistant referees.
It is quite clear that Frank Sinclair saw an opportunity for this match to be officially abandoned and played again, and that he chose to reject any options given to both teams for the game to be finalized. I hope the FA realize that this game could have been completed, but history is not on our side with such FA decisions. I think we should make it quite clear that we do not not see why we should play the game again, from 0-0.
