Parent article: The GPL Is a License, not a Contract
The conditions for terminating a license are given in USC 17 203. It must be done within a 5 year period between 35 and 40 years after the grant was mode. It must be agreed to by a majority of the copyright holders. You must send out a written notice in advance.
And even then, 203b1 says that any derivative work made before the termination made can be distributed and modified under the terms of the (terminated) license. Since the GPL's granted rights are transitive, this means anyone receiving it from you has the full rights of the GPL.
An implied contract is the only thing I know of that would allow you to defend continuing to re-distribute under the old license.
Or, perhaps, you know. Copyright law.
