Michael Jackson faces a contempt of court charge after failing to appear at a hearing in a case brought by a man who claims he was abused by the singer.
Michael Jackson was cleared of child molestation charges in June
Mr Jackson or a lawyer representing him had been summoned to appear in court in Louisiana.
Joseph Bartucci alleges he was lured into Mr Jackson's limousine in 1984 and sexually assaulted.
Mr Jackson's spokesman blamed the no-show on an "administrative error" and rejected the claims.
"Michael Jackson has had many such lawsuits and each one has resulted in him being exonerated or the case being dismissed," said Brian Oxman.
"This is part of the magic and burden of being Michael Jackson."
District Judge Eldon Fallon set a hearing for 17 August in which Mr Jackson must show why he should not be held in contempt of court.
Mr Bartucci claims that when he was 18 he was assaulted by the singer and held against his will for several days.
His legal action contends that he had suppressed the memories until two years ago when they were triggered by news coverage of the recent child molestation case against Mr Jackson.
Mr Jackson, 46, was acquitted of all child molestation charges against him.
Meanwhile, Mr Jackson has said he will not be attending a birthday party which is being held for his father, Joseph, this weekend in Berlin.
A statement on his official website said: "Michael would like to wish his father a very heartfelt 'Happy Birthday' and he hopes that everyone attending the event has a truly wonderful time."
