To pavane

You are nearly correct about the duties etc of MCPS but they are, like the MU (for instance) a rather toothless old dog.

CM (if they have "put into distribution" an item which in itself infringes copyright) or indeed anyone infringing copyright commits a CRIMINAL offence quite aside from any civil action brought by a third party. The Copyright Designs and Patent Act of 1986 details all the relevant ways of infringement and the penalties for doing so.

From what I am led to understand, the chances of MCPS doing anything whatsoever are limited to put it mildly. There are other routes to focus the attentions of actual and would-be infringers and that is in the first instance via the local Trading Standards department. If they can be convinced that infringing items are in existence, it is within their power to enter premises under an Anton Pilar order and "remedy" the situation.

We are all likely to evaporate before MCPS or PRS decamp from their cosy armchairs.
