HOUSTON -

Liquor stores in Texas have always been closed on Sundays, but that could soon change.

A state representative from Houston has proposed new hours to open liquor stores seven days a week.

State Rep. Senfronia Thompson, D-Houston, represents the 141st District, which covers northeast Houston and Humble.

Thompson said allowing liquor stores to open on Sundays would increase the state's revenue.

"In a modern economy, blue laws and hour restrictions on sales no longer make sense," Thompson said. "Allowing spirits retailers to keep additional hours is not only the fair thing to do, but will also generate new revenue for Texas."

"Spirits" retailers are only allowed to open 66 hours per week, but beer and wine retailers are allowed to make sales up to 115 hours per week.

"Texas should make hours of operation more even for the sale of all products and not unreasonably and unfairly restrict one from the other," Thompson said.

According to a 2011 Texas Legislative Budget Board report, Texas could gain up to $8 million in new revenue by expanding liquor store hours.

If Thompson's proposal is approved, liquor stores would be open from noon to 10 p.m. on Sundays. Liquor stores would continue to remain closed on Thanksgiving, Christmas and New Year's Day.
