Kokua Line: Why did I pay both agents when selling home?

Question: Last year I sold my mother’s home, and I paid commissions to the buyer’s agent and my agent. Isn’t there a new rule stipulating a seller is no longer responsible for paying the commission to a buyer’s agent? Can I get reimbursed for the buyer’s agent’s commission, or do I need to file a class- action lawsuit?
