Same-sex marriage pioneer Edie Windsor has remarried.

87 year old LGBT activist Edie Windsor married Judith Kasen, a vice president at Wells Fargo Advisors, at City Hall in New York earlier this week.

The activist became well known after she filed a lawsuit against the federal government. Ms Windsor sued the government in order to get the federal estate tax deduction previously only available to straight people when their spouses die.

She made the move after receiving a $363,000 estate-tax bill after her first wife, Thea Spyer, passed away in 2009.

Her case was taken to the Supreme Court and resulted in the decimation of the Defence of Marriage Act 2013.

The newlyweds have been receiving congratulatory messages across social media.

Executive Director of Marriage Equality USA, Brian Silva, said: “I can’t think of anyone more deserving of this joy and happiness. We wish Edie and Judith many years of health and happiness.”

Windsor set up a scholarship fund to teach more queer women to code.

Ms Windsor has spoken about how honoured she felt to represent the LGBT community when she won her law suit. “I was honoured and humbled and overjoyed to represent not only the thousands of Americans whose lives have been adversely impacted by the Defense of Marriage Act but those whose hopes and dreams have been constricted by the same discriminatory law.”

Section 3 of DOMA, which defined marriage as between one man and one woman, was deemed unconstitutional and pave the way for over 1,100 benefits previously not afforded to same-sex couples.

The case helped give same-sex couples more rights and paved the way to legalising equal marriage across America.
