The trial of Dr Conrad Murray officially begins today, he is accused of delivering a fatal dose of anaesthetic to Michael Jackson.
Proceedings also will be televised and broadcast online.
During a pre-trial hearing last night, Nareg Gourjian, a lawyer for Murray, claimed that Jackson was unconscious backstage before his March 2009 London news conference for his This Is It concert series, and that he appeared drunk during the announcement itself.
Judge Michael Pastor, presiding over Murray's trial, has ruled that tape of the alleged incident should not be shown to jurors. The rationale being that the video was irrelevant, because it occurred months before Jackson died.
