WASHINGTON — President Obama has nominated William Kayatta Jr. of Cape Elizabeth to fill Maine’s seat on the U.S. 1st Circuit Court of Appeals, the White House announced Monday.

Kayatta, 58, is a nationally prominent trial attorney and a partner in the Pierce Atwood law firm in Portland. He was one of two people whom Maine lawmakers recommended to Obama in late May. It took the White House nearly eight months to make the nomination.

If confirmed by the Senate, Kayatta would replace Judge Kermit Lipez, who has served in Maine’s seat on the appellate court since 1998. Lipez shifted to “senior,” semi-retired status Dec. 31 but has said he will carry a full caseload until September.

The nation’s 12 circuit courts are just a step below the U.S. Supreme Court and are the final stop for most cases appealed from federal district courts, since few cases reach the Supreme Court.

Circuits courts consider a wide range of issues, from businesses appealing tax law rulings to employees claiming workplace discrimination to police brutality cases. The 1st Circuit has six full-time judges, the fewest of any circuit court, and covers Maine, Massachusetts, New Hampshire, Rhode Island and Puerto Rico.

Kayatta has lost just two trials in 30 years, according to his biography on Pierce Atwood’s website. In addition to his trial work, he has argued 37 cases on appeal, including two before the U.S. Supreme Court, and won 31 of those appeals, according to Pierce Atwood.

Last year, Kayatta was named by the Supreme Court to be the special master overseeing a case involving the state of Kansas suing Nebraska, claiming it was overusing water in the Republican River basin. A special master operates like a trial judge and recommends how the Supreme Court should proceed.

In 2010, Kayatta received the Maine State Bar Association’s Howard H. Dana Jr. Award for his work as a pro bono attorney on behalf of disabled Maine children, and for his leadership in the broader effort to increase access to justice for all Maine residents.

In 2000, he defended several manufacturers of the gasoline additive MTBE, including Arco Chemical and Lyondell Chemical. In that case, a state judge dismissed a request for class-action status for a lawsuit seeking to have the manufacturers pay to test 25,000 wells in Maine for contamination from MTBE, and to clean up any contamination found, according to an Associated Press report at the time.

Kayatta graduated from Amherst College in 1976 and from Harvard Law School in 1979.

His nomination drew praise Monday from Maine’s two senators, Republicans Susan Collins and Olympia Snowe. While the nomination process can slow in an election year, support from both home state senators could smooth Kayatta’s path to confirmation.

Circuit court nominees have been waiting an average of about 10 months to get Senate confirmation votes, so it isn’t certain that Kayatta’s nomination will get a vote before November’s election, said Carl Tobias, a law professor at the University of Richmond and an expert on judicial nominations.

The Senate confirmation process traditionally grinds to a halt by August of an election year, he said, because the party that’s not in the White House is in no rush to confirm judicial nominees just before the election, Tobias said.

He also noted that Senate Republicans were angered by Obama’s appointment of Richard Cordray, during Congress’ year-end recess, to head the Consumer Financial Protection Bureau. He said that could slow the nomination process further this year.

However, Collins’ and Snowe’s strong support for Kayatta could help persuade Republican leaders in the Democratic-controlled Senate to allow his nomination to move forward before August, Tobias said.

Kayatta declined to comment Monday.

Collins said Kayatta is “eminently qualified to serve on the 1st Circuit Court of Appeals” and called on Republicans and Democrats to support his nomination.She said that she hopes election-year politics won’t get in the way of Kayatta’s confirmation, and that she is trying to pave the way for Kayatta in the Senate.

“I have already begun discussing Bill with my colleagues, and I am optimistic that his extraordinary qualifications will trump partisan gridlock,” Collins said via email Monday evening.

U.S. Reps. Mike Michaud and Chellie Pingree, both Democrats, recommended in May that Obama nominate either Kayatta or Maine Supreme Judicial Court Justice Jon Levy to the 1st Circuit seat.

The Senate confirms judicial nominees, but because both of Maine’s senators are Republicans and Obama is a Democrat, it is up to Pingree and Michaud to recommend federal judicial nominations to Obama.

The Senate confirmed another Mainer to a federal court seat last year.

Nancy Torresen, a former assistant U.S. attorney from Bangor, won confirmation Oct. 3 to the U.S. District Court for Maine.

There are 36 judicial nominees pending in the Senate, 18 of them awaiting Senate votes and 18 still pending in committee, according to the Senate Judiciary Committee.
