Intelligence Oversight and Accountability Act of 2013 - Amends the Foreign Intelligence Surveillance Act of 1978 (FISA) to revise congressional reporting requirements with respect to FISA court decisions.
Requires the Attorney General (DOJ), within 45 days after the Foreign Intelligence Surveillance Court or the Foreign Intelligence Surveillance Court of Review issues a decision, order, or opinion that includes a denial or modification of a request for an order, or that results in a change of application or a new application of FISA, to submit to Congress a copy of such decision and any associated pleadings, applications, or memoranda of law. (Currently, the Attorney General submits such materials only with respect to decisions that the Attorney General determines are a significant construction or interpretation of FISA.)
Directs the Attorney General to include with such court documents a brief statement (a summary) of the relevant background factual information, questions of law, legal analysis, and decision rendered.
