A judge has ruled that Apple CEO Tim Cook must sit for a deposition in the U.S. government’s lawsuit against the company over alleged price-fixing in the ebook market, reports “Reuters” (http://tinyurl.com/d5888dg).

U.S. District Judge Denise Cote in Manhattan granted the Justice Department’s request to compel Cook to testify for four hours in the lawsuit, which accuses Apple of conspiring with five publishers to raise e-book prices. The government had argued that Cook likely had relevant information about Apple’s entry into the e-books market.

Apple fought the request, saying Cook’s testimony would be “cumulative and duplicative” since the government had already deposed 11 other executives at the iPad maker, notes “Reuters.”
