Bromwich was one of two names picked by the Justice Department as well as plaintiff states as part of last month's injunction ruling. As monitor, he'll work from inside Apple to maintain the company's compliance with US antitrust laws.
Bromwich filled a similar, independent monitor role within the Metropolitan Police Department of the District of Columbia a little more than a decade ago, and more recently served as part of US oversight on the oil industry.
Apple previously argued that an external monitor was wholly unnecessary, but ultimately failed to persuade Cote.
Bromwich will keep an eye on Apple's antitrust compliance for two years. Note that the two-year period is less than the five-year period initially proposed by the DOJ.
Lastly, Apple earlier this month filed a motion indicating that it plans to appeal Cote's ruling. Formal arguments on the matter, however, won't be submitted until early 2014.
