A heterosexual Jewish couple who want to enter a civil partnership rather than get married have been allowed to take their case to the Supreme Court.

Rebecca Steinfeld, 36, and Charles Keidan, 40, launched a judicial review in December 2013 after rejecting traditional marriage — believing it to be sexist — and applying to register their union in a civil ceremony.

In February, the Court of Appeal ruled that heterosexual couples were not allowed to be in civil partnerships.

If the Supreme Court overturns the previous judgment, the west London couple, who have a daughter and another child on the way, will be allowed to enter a secular partnership.

Ms Steinfeld and Mr Keidan said the civil partnership, which came into law for same-sex couples in 2005, “captures the essence of our relationship and values”.

They view the arrangement as a “simple, modern contract conferring almost identical rights and responsibilities as marriage” but without its social pressures.

Mr Keidan said: “Over the last few years, we’ve heard the same message: whilst most couples want financial and legal protection for themselves and their families, not all feel comfortable with marriage.”

Ms Steinfeld added: “We hope the Supreme Court will deliver a judgment that will finally provide access to civil partnerships for thousands of families across the country.”

Their solicitor, Louise Whitfield, said bringing the case to the Supreme Court, which hears a small number of cases each year, was a “significant achievement”.

The case is expected to be heard in the first half of 2018.
