During its 2009 term (commencing in October 2009 and extending until June 2010), the United States Supreme Court decided four cases focusing on arbitration, suggesting that the Court continues to exhibit a strong interest in developing arbitration jurisprudence. The theme of the year's decisions, if there is one, can be reasonably said to be allocation of responsibility for determining arbitrability. The Supreem Court's decisions this year are discussed in more deatil below in chronological order.
