Languages: English

Mr. Tynan joined Montgomery Barnett in 1999, after twenty-five years of practice as a partner in his own and other law firms in New Orleans. He is engaged in an admiralty and maritime practice involving marine insurance coverage, hull and machinery claims, collisions, groundings, property damage, and maritime product liability cases, as well as charter parties, maritime liens and protection and indemnity defense matters. He also has experience before the Office of Administrative Law Judges for the U.S. Coast Guard in license suspension and revocation hearings, and with employment discrimination claims, particularly as they involve maritime clients. Prior to passing the bar, Mr. Tynan sailed as an ordinary seaman and helmsman in the deck department of U.S. flag merchant vessels.

Mr. Tynan is a member of the bars of the states of both Louisiana and Texas, and is admitted to practice before the U.S. Supreme Court, the U.S. Courts of Appeal for the Fifth and Eleventh Circuits, the U.S. District Courts for the Eastern, Middle and Western Districts of Louisiana, and the U.S. District Courts for the Northern, Southern, Eastern and Western Districts of Texas. He has tried a number of cases in state and federal courts in Louisiana, and in federal courts in Alabama, Mississippi, Tennessee and Texas.

Mr. Tynan successfully presented the case of First Nat’l Bank of Jefferson v. M/V LIGHTNING POWER, 776 F.2d 1258 before the U.S. Court of Appeals for the Fifth Circuit, which refined the standards under which a district court may set aside for an insufficient price a public auction by the U.S. Marshal of a vessel under arrest. He also successfully argued the case of Nicholson Mgt. & Consultants, Inc. v. Bergman, 96-0557 (La. App. 4th Cir. 9/25/96), 681 So.2d 471, writ den., 96-2588 (La.1/6/97) 685 So.2d 126, which is the only case to interpret and determine the prescriptive period or statute of limitations for an oblique or third-party action brought under Articles 2041 and 2044 of the Louisiana Civil Code.

Born on January 16, 1949 in Boston, Massachusetts, Mr. Tynan received his Bachelor of Arts degree from the University of Notre Dame, Notre Dame, Indiana, in 1970, and was awarded his Juris Doctor by the Tulane University School of Law in 1974.
