A former owner of the Annandale Hotel has launched an expletive-laden spray at Leichhardt Municipal Council, which reversed its long opposition to live music after the receivers finally moved in to sell the business.

Matthew Rule's online remarks follow a unanimous vote by council this week to adopt a "Good Neighbour Policy" to end legal action against music venues.

It's a marked departure from the council's combative encounters with Mr Rule and his brother Daniel that took a financial toll in the years they owned the Annandale.

Mr Rule had previously complained about fighting council on everything from development applications to outdoor seating. A protracted Land and Environment Court battle over late-night trading and noise compliance cost the brothers more than $200,000.
