Egyptian President Mohamed Morsy has issued an order preventing any court from overturning his decisions, essentially allowing him to run the country unchecked until a new constitution is drafted, his spokesman announced on state TV Thursday.

Morsy also ordered retrials and reinvestigations in the deaths of protesters during last year's uprising against strongman Hosni Mubarak. That could lead to the reprosecution of Mubarak, currently serving a life prison term, and several acquitted officials who served under him.
