If you look at it from a logical view point, forgetting specific 'rules' and thinking about it from a footballing point of view; the question you have to ask is did varsity gain an advantage by fielding this player? From the sounds of things - he has been there the whole season and will stay there for the near future at the very least. With this in mind - were any other team disadvantaged by his non complete registration?
Answer to both questions is no.
Does the punishment fit the crime? Has justice really been served?
Not only taking all their points for the season - which breaks one of mainlands own rules (2.6) - but also docking them a further 15 points - for failing to send in some paperwork?
Are we not all here because of our love for the game? The passion, the glory, the commitment and hard work. Is that to be considered second to 'administration' now?
This is a bad example to be set by Mainland Football and a downright abuse of power.
You wanna settle this fairly?
Dock uni 3 points as a warning for their error - that would make for a VERY interesting continuation of the season for all teams involved.
