OK, so nobody else seems to be interested in this, so I checked again.
The handbook on the PL website is definitely the July version without the changes made in November to make the rules "lawful". So the new amended version, which was posted last week, has been removed.
Of course, this could just be a mistake by PL (likely I suppose): either posting the amended version in error last week, or removing the link to the amended version in error this week.
Or, it could mean the FA haven't approved the amended rules yet, which would already be unusual.
Or, and bear with me, the tribunal has agreed with City that the APT rules as a whole are unlawful and so the amended rules had to be taken down. The consequences of that would be total victory for City in the APT case and total chaos for the PL.
Let's wait and see what happens.
