Dome contract, the government sued in 1924 to cancel the arrangement with Mammoth. The trial court held the lease legal and dismissed the complaint; but in 1927 the U.S. Supreme Court, on appeal, voided the contract on technical grounds, though finding "no direct evidence of fraud." A jury which deliberated only forty minutes acquitted Mr. Sinclair of a criminal charge of conspiracy to defraud. The use by Mr. Sinclair of private detectives to keep the jury under observation during the trial drew a sentence for contempt of court. During the long controversy, Mr. Sinclair gave 175,000 words of testimony before twelve legislative committees, disdaining the fifth amendment; but for refusing to answer one question which his counsel considered not to be pertinent to the legislative inquiry, Mr. Sinclair was held to be in contempt of the Senate. On the contempt citations, he spent six and one half months in the Washington, D.C. House of Detention in 1929.
