Gay marriage supporters are planning rallies across California on Tuesday to coincide with a ruling on Proposition 8, California's gay marriage ban.

The three-judge panel of the Ninth Circuit Court of Appeals is expected to hand down its decision on the constitutionality of the 2008 voter-approved amendment Tuesday at 10AM. The ruling most likely won't end the legal wrangling, because an appeal to the United States Supreme Court is expected.

After now retired U.S. District Judge Vaughn R. Walker declared the law unconstitutional in 2010, proponents of the amendment appealed the ruling.

“We are very hopeful that the Ninth Circuit will rule in favor of fairness and equality, once and for all putting an end to Prop 8's exclusion of loving, committed couples from marriage,” John Lewis, legal director for Marriage Equality USA, said in a statement.

Supporters in San Francisco were planning two events, a 10AM gathering on the steps of the Ninth Circuit Federal Courthouse and an evening rally at Market Street and 17th Street. Organizers in Los Angeles are planning a 6PM rally at West Hollywood Park. Similar events were being planned in communities across California, including Fresno, Sacramento, San Diego and Santa Barbara.
