I can't really think of any "wholesale all lobbying forbidden", but at least for specific industries there are a couple. "WHO FCTC Article 5.3" which is about limiting the influence of tobacco companies is probably the first that comes to mind, and the most famous example. Singapore I think recently done some legislative changes around lobbying as well, but I'd confess to not knowing much about it, maybe someone here could fill out the blanks if they have the knowledge already.
