The U.S. Supreme Court has declined to hear a case brought by casino mogul and Trump ally Steve Wynn, effectively upholding the landmark 1964 New York Times v. Sullivan ruling on defamation. Wynn had sought to challenge the 'actual malice' standard, which requires public figures to prove that statements made against them were published with knowledge of their falsity or with reckless disregard for the truth. The case stemmed from a defamation lawsuit Wynn filed against The Associated Press over a story about sexual misconduct allegations against him dating back to the 1970s. The Nevada Supreme Court had previously upheld a ruling dismissing Wynn's lawsuit, finding that the AP had published the article in good faith. In a separate decision, the Supreme Court also refused to revive a lawsuit filed by young climate activists against the federal government. The lawsuit, known as Juliana v. United States and named after plaintiff Kelsey Juliana, argued that government policies exacerbating climate change violated the constitutional rights of the plaintiffs. The case, which began in 2015 with 21 young plaintiffs, was dismissed by the 9th U.S. Circuit Court of Appeals, which ruled that the youths lacked legal standing to sue. The Biden administration had urged the dismissal of the suit. The Supreme Court's decision not to hear the appeal marks the end of a decadelong legal battle.
