A trademark dispute over a poop-themed dog toy shaped like a Jack Daniel’s whiskey bottle coming before the U.S. Supreme Court could redefine how the judiciary applies constitutional free speech rights to trademark law.

In a case to be argued on Wednesday, the nine justices are expected to use this legal dogfight to clarify the line between a parody protected by the U.S. Constitution’s First Amendment and a trademark-infringing ripoff, with repercussions extending beyond booze and pet accessories. A ruling is due by the end of June.

Jack Daniel’s Properties Inc, owned by Louisville, Kentucky-based Brown-Forman Corp (BFb.N), is appealing a lower court’s decision that Phoenix-based VIP Products LLC’s “Bad Spaniels” chew toy is an “expressive work” protected by the First Amendment.
