WASHINGTON: The US Supreme Court on Tuesday declined to hear a California Republican club's challenge to a private organization's cancellation of a 2017 event at a city-owned property in Pasadena that was to have featured a conservative lawyer later aligned with former President Donald Trump.

The justices turned away the Pasadena Republican Club's appeal of a lower court ruling that found that the cancellation of attorney John Eastman's planned appearance did not violate the U.S. Constitution's First Amendment, which bars government discrimination on free speech or religious grounds.

Eastman played a role in Trump's failed bid to overturn his 2020 re-election loss based on false claims of widespread voting fraud.

The property at issue, the Maxwell House, is owned by the city of Pasadena, which leased it to the Western Justice Center, a nonprofit organization that focuses on conflict resolution. Space in the Maxwell House is made available for rent for events including weddings.

The Pasadena Republican Club had wanted to rent space there so Eastman could appear as a guest speaker, but the Western Justice Center canceled the event because his opposition to same-sex marriage and other expansions of LGBT rights ran counter to the group's values.

Eastman was a professor at Chapman University School of Law at the time. Eastman is the chairman of the board of the National Organization for Marriage, which was active in the fight against legalizing gay marriage.

In the Republican club's 2018 lawsuit, its lawyers said the First Amendment applied because the Western Justice Center was effectively an arm of the government based on its lease of city property. The San Francisco-based 9th U.S. Circuit Court of Appeals in February ruled against the Republican group.
