Nobody said that Clarkson is being obstructionist about it. Even when all parties are amicable *and* want the work to proceed, dealing with writer's rights, crediting and pay after the writer has been terminated is a rather complex issue that can take considerable time to sort out. Firing an on-camera personality is simple, firing a writer whose creation you are going to continue to use (even if he or she wants you to use it and doesn't want anything they haven't already gotten from you) is complex and legally difficult if you want to keep using the material they created. This is the part I would have expected to take the BBC the three weeks to sort out, not the 'investigation'.
