City of Houston officials must count the signatures on a petition filed by anti-gay activist Dave Wilson, who is seeking a vote to amend the city charter and bar men "who perceive or express themselves as women" from entering women's restrooms, a judge ruled Tuesday. State District Judge Brent Gamble ruled Tuesday that City Secretary Anna Russell has a "nondiscretionary ministerial duty" to count and certify the signatures Wilson submitted in early July, and to present the count to City Council by Aug.
