Maryland?s chapter of the American Civil Liberties Union threatened legal action against Baltimore County if officials allow a newly passed bill limiting the life span of political signs to take effect.

Members of the County Council earlier this week passed a bill limiting the display of campaign signs on private property to 45 days before a primary election. The bill ? a downscaled version of a proposal that included restrictions on sign size and the number of signs per yard ? is scheduled to take effect Feb. 1.
