Last week, the executive director of the Chicago Board of Ethics told the mayor and aldermen they could buy Cubs playoff tickets at face value provided they went to the game themselves and were publicly acknowledged by having their names announced or displayed.

A new ethics interpretation, however, will take effect before the Cubs face the Dodgers in game six of the seven-game series. In a revised memorandum, the Board of Ethics said the elected officials may accept the tickets at face value only if they perform a ceremonial duty or action and there is a clear and direct connection between the official’s attendance and performance of such ceremonial duty or action.
