Quote Derwent="Derwent"
How can a "club" hold a player's registration when the "club" does not exist as a legal entity '"
You've got it back to front. What holds the player registrations is the legal entity that owns and runs the business. To put it another way, if it holds the registrations, then it exists. You just need to know what you're talking about in the relevant context.
The reason I referred to "club" was because in this context it seems sensible to use the same terminology as the RFL do when talking about their rules.
Quote Derwent“Club” means any Member which is a Rugby League Club and any other Rugby League
Football club or other body which may be invited to join the RFL from time to time in
accordance with these Bye Laws;'"
... and ...
Quote Derwentwhere a Player is registered to an entity which is not a Club that entity shall be bound by these Rules and any other applicable Rules as if it were a Club.'"
I hope this goes some way to lessen your confusion.
Quote Derwent="Derwent" Surely the registration is (was) held by the company as the "club" could not have employees ?'"
All you need to get your head around is that a limited company is a legal person, just like a real live person. Fred Bloggs could run a dozen different businesses, all trading under different names. let's say one of them is called "Club Derwent". An employee could well be employed by "Club Derwent" if that's how he ran it,
the legal entity would be "
Fred Bloggs trading as Club Derwent", and that would be the reality, though the name everyone would know was simply "Club Derwent". Nobody would ever use the long version.
Fred could get fed up of running Club Derwent, and sell the business to Joe Brown. See what he did there? Club Derwent is what the employees and customers know and love, and carries on uninterrupted. It had, and has, employees. Now the contracts have all been TUPE'd to Joe Brown. The business, including the burden of employees contracts, has been acquired by a new owner.
If Club Derwent had been a member of some other body, (like the RFL) that body might want to have a look at who the new owners of Club Derwent are, before confirming whether they are cool with the membership having been transferred to a new member, and if they are, then Club Derwent's membership of that body does indeed remain uninterrupted.
