Peter Pan went into public domain in Britain this year

Would you like to get good and disgusted? This is a Newsarama comments thread that is mostly complaining that DC lost the case.
And if you want truly scary copyright weirdness, check out this article on James Joyce's grandson, who has been hovering over his grandfather's work like a vulture.
The provisions of Schedule 6 have effect for conferring on trustees for the benefit of the Hospital for Sick Children, Great Ormond Street, London, a right to a royalty in respect of the public performance, commercial publication, broadcasting or inclusion in a cable programme service of the play 'Peter Pan' by Sir James Matthew Barrie, or of any adaptation of that work, notwithstanding that copyright in the work expired on 31 December 1987.
However the Hospital also commissioned an 'offical sequel' in 2004, "Peter Pan in Scarlet", featuring the same characters, which has the effect of extending their copyright on the characters until... probably some time in the 22nd century
am I the stupid one now?
The idea of "promoting the useful arts" is nothing more then preamble, it does not dictate the character of copyright law anymore then "to form a more perfect union" dictates the character of every law.
Copyright extension is constitutional. Does not mean you have to like to like it, obviously, but its now well settled congress has the right to do so. Anyway, thats the fact of it, lets not turn this thread into a copyright war thread.
