LOS ANGELES: Two weeks after Michael Jackson's death, administrators of his estate are temporarily authorized to reopen for business and negotiate, among other things, agreements relating to the singer's ill-fated "This Is It" concert tour.

While fans in London on Monday lit candles and placed flowers outside the 02 Arena where the entertainer was due to begin his run of 50 concerts, lawyers were in a Los Angeles Superior Court ironing out details of the powers given to two men named by Jackson to administer his estate.

Superior Court Judge Mitchell Beckloff conferred wide-ranging authority on attorney John Branca and recording executive John McClain, at least until Aug 3.
