A federal judge Thursday struck down Virginia’s constitutional amendment that defines marriage as between a man and a woman as unconstitutional.

“The court is compelled to conclude that Virginia’s marriage laws unconstitutionally deny Virginia’s gay and lesbian citizens the fundamental freedom to choose to marry,” said Judge Arenda L. Wright Allen of the U.S. District Court for the Eastern District of Virginia. “Government interests in perpetuating traditions, shielding state matters from federal interference, and favoring one model of parenting over others must yield to this country’s cherished protections that ensure the exercise of the private choices of the individual citizen regarding love and family.”

Allen, who President Obama nominated to the federal bench in 2010, repeatedly referenced the U.S. Supreme Court’s landmark 1967 ruling that struck down Virginia’s interracial marriage ban in her 41-page decision. She also opened her decision with a quote from Mildred Loving, who publicly backed marriage rights for same-sex couples before her death in 2008.

“Tradition is revered in the commonwealth, and often rightly so,” said Allen. “However, tradition alone cannot justify denying same-sex couples the right to marry any more than it could justify Virginia’s ban on interracial marriage.”

Allen also dismissed arguments made by those who defend Virginia’s same-sex marriage ban that marriage rights for gays and lesbians harms children.

“Of course the welfare of our children is a legitimate state interest,” she said. “Limiting marriage to opposite-sex couples fails to further this interest. Instead, needlessly stigmatizing and humiliating children who are being raised by the loving couples targeted by Virginia’s Marriage Laws betrays that interest.”

Allen’s ruling comes less than two weeks after she heard oral arguments in a lawsuit that Timothy Bostic and Tony London of Norfolk and Carol Schall and Mary Townley of Chesterfield filed last year.

“We want to be married for the happy times, but we need to be married for the sad times,” Schall told the Washington Blade earlier this month before Wright heard oral arguments in their case. “When one of us is sick or when one of us needs surgery or when health care is an issue, we need to be there for each other. And Virginia should not be in the business of standing in the way of people wanting to care for each other and take responsibility for each other.”

Virginia voters in 2006 approved the marriage amendment by a 57-43 percent margin.

Attorney General Mark Herring last month announced he would not defend the amendment.

The Republican-controlled Virginia House of Delegates earlier this month overwhelmingly approved a bill that would allow any state lawmaker to defend a law if the governor and attorney general decline to do so. Gov. Terry McAuliffe a few days earlier denied a request from 30 state lawmakers to appoint a special counsel to defend the marriage amendment.

A federal judge in Harrisonburg on Jan. 31 certified a second lawsuit the American Civil Liberties Union, Lambda Legal and the ACLU of Virginia filed on behalf of two lesbian couples from the Shenandoah Valley who are seeking marriage rights in the commonwealth as a class action.

“This decision is a victory for the Constitution and for treating everyone equally under the law,” said Herring in a statement after Allen issued her ruling in the Bostic case.

McAuliffe also applauded the decision.

“In order to grow our economy and attract the best businesses, entrepreneurs, and families to Virginia, we must be open and welcoming to all who call our commonwealth home,” he said in a statement. “As this case continues through the judicial process, I will enforce the laws currently on the books, but this decision is a significant step forward in achieving greater equality for all of our citizens.”

Former U.S. Solicitor General Ted Olson, who successfully argued against California’s Proposition 8 before the U.S. Supreme Court with David Boies, joined the lawsuit last September with the American Foundation for Equal Rights. Olson said in an AFER press release that Allen’s decision has “upheld the principles of equality upon which this nation was founded.”

“Virginia’s prohibition on marriage for same-sex couples relegates gay and lesbian Virginians to second-class status,” he said. “Laws excluding gay men and lesbians from marriage violate personal freedom, are an unnecessary government intrusion, and cause serious harm. That type of law cannot stand.”

Equality Virginia Executive Director James Parrish said Wright’s ruling “finally puts Virginia on the path toward allowing lesbian and gay couples to marry the person they love here in the place they call home.”

“This is an historic day in Virginia,” added Parrish.

National Organization for Marriage President Brian Brown blasted Allen.

“This is another example of an Obama-appointed judge twisting the constitution and the rule of law to impose her own views of marriage in defiance of the people of Virginia,” said Brown in a statement.

Brown also again sharply criticized Herring for not defending the commonwealth’s marriage amendment.

“This case also leaves a particular stench because of the unconscionable decision of Attorney General Mark Herring to not only abandon his sworn duty to defend the laws of the state, but to actually join the case against the very people he is duty-bound to represent,” said Brown.

Victoria Cobb, president of the Family Foundation of Virginia, also criticized Herring.

“Regardless of one’s stance on marriage, the people of Virginia were disenfranchised by this ruling as our voice and our vote that amended our Constitution have been rendered meaningless by a single federal judge with the assistance of our own attorney general,” she said.

Neighboring Maryland is among the 18 states and D.C. that have extended marriage rights to same-sex couples.

The Southern Poverty Law Center earlier on Thursday filed a federal lawsuit against Alabama’s same-sex marriage ban on behalf of a gay widower who married his late-husband in Massachusetts in 2011.

A federal judge on Wednesday ruled Kentucky must recognize same-sex marriages legally performed in other states.

Gays and lesbians in West Virginia, Utah, Pennsylvania, Florida, Missouri, Louisiana and other states have filed lawsuits seeking marriage rights in the wake of the U.S. Supreme Court’s landmark decision last June that found a portion of the Defense of Marriage Act unconstitutional. Nevada Attorney General Catherine Cortez Masto earlier this week announced she will no longer defend her state’s same-sex marriage ban in court.

Attorney General Eric Holder on Feb. 10 announced the Justice Department will now recognize same-sex marriages in civil and criminal cases and extend full benefits to gay spouses of police officers and other public safety personnel. This directive applies to Virginia and the 31 other states that have yet to allow nuptials for gays and lesbians.

U.S. Sen. Ted Cruz (R-Texas) earlier on Thursday introduced a bill that would ban the federal government from recognizing same-sex marriages in states that ban gay nuptials.

Allen has stayed her ruling, pending the outcome of an appeal.
