Judge dismisses majority of sexual assault lawsuit against Steven Tyler

The majority of a sexual assault lawsuit filed against Steven Tyler has been dismissed in a Los Angeles court.

According to documents obtained by People magazine, a judge ruled that Julia Misley's complaint against Tyler, which included various claims regarding an alleged sexual relationship with the rock star when she was a teen in the 1970s, would only move forward with one claim.

"This is a massive win for Steven Tyler. Today, the Court has dismissed with prejudice 99.9 per cent of the claims against Mr Tyler in this case," Tyler's lawyer told the outlet in a statement.

"The court has decided that only one night, 50-plus years ago, out of a three-year relationship is allowed to remain. We look forward to trying this case on 31 August."

Per the filing, the intentional infliction of emotional distress (IIED) claim that remains in Misley's lawsuit centres around an allegation that she and Tyler had sex in a hotel and public hot tub when she was 16 in California in 1974.

The filing claims that they were "engaged to be married, expecting a child and still living together in Massachusetts", in June 1975. Misley alleges she was coerced into terminating the pregnancy.

Misley did not initially name Tyler in her lawsuit, but her allegations aligned with comments he made in his 2011 memoir Does the Noise in My Head Bother You? about a relationship with a 16-year-old girl.

The I Don't Want to Miss a Thing wrote that he "almost took a teen bride" because "her parents fell in love with me, signed a paper over for me to have custody, so I wouldn't get arrested if I took her out of state. I took her on tour with me."

Tyler has denied all claims against him and insisted that Misley consented to their sexual relationship.
