According to a judge's ruling, a candidate in Gulfstream Town Council can post his campaign signs within the Delray Beach city limits. City officials were picking them up as he wasn't a candidate in Delray Beach, but he claimed freedom of speech. He got a hearing so quickly since time was of the essence, given that the election is next week.
The ruling makes sense on First Amendment grounds. And I remember many times seeing overlap between West Palm Beach and Lake Worth candidate signs, especially in the area of south West Palm Beach and the north part of Lake Worth. Click title for link. I guess the Gulfstream candidate is quite notorious.
