On 22 May, President Obama signed into law the Iran Nuclear Agreement Review Act of 2015. The new U.S. legislation comes just over a month after the announcement of a framework for an agreement on nuclear issues between Iran and, the European Union and the P5+1 (or E3+3) powers (the U.S., UK, France, China, Russia and Germany). The legislation, which passed with bipartisan support in Congress and the support of the White House, defuses concerns that the U.S. Congress would attempt to pre-empt President Obama’s authority to agree to any deal with Iran that eases sanctions. More details on the legislation and the agreed framework for  the negotiations with Iran are discussed in our client update of 15 May 2015.
