North London's Camden Council is seeking to bring anti-social behaviour orders against Sony and BMG executives who it alleges are responsible for illegal billposting on the borough's walls and streets.
If successful, music advertising executives could face a custodial sentence and the ASB orders would set a precedent throughout England and Wales.
The city borough insists such postings, one of many "guerrilla marketing" tactics, saves Sony and BMG between £3 million ($5.53m; €4.50m) and £6m compared to the cost of using more conventional media.
Existing legislation is seen to be lacking in substance with the maximum fine being only £2500. Whereas Camden claims to have spent £250,000 tackling the problem.
Lawyers representing the council have already received the blessing of a district judge to bring the case to court, and interim and permanent orders preventing such billposting will be sought on June 14.
