U.S. Pacific Fleet commander Adm. Thomas Fargo denied testimonial immunity for the commander of the Navy submarine involved in a collision with a Japanese fishing vessel.

Navy officials said that Fargo rejected Cmdr. Scott Waddle's request for immunity.

It is unclear whether Waddle will decide to testify despite the decision. Waddle's attorney Charles Gittins had said that his client would not testify unless he was given immunity.

Before Monday's inquiry session began, Waddle told reporters that he would take responsibility for the Feb. 9 collision between the Greeneville and Japanese trawler Ehime Maru, which left nine crew members missing and presumed dead.

"If Adm. Fargo should choose to grant me testimonial immunity, and I am afforded the opportunity to take the stand under oath, the first words that I say to the court will be that fact, that I am accountable, I am responsible for the actions that led to the tragic collision and sinking of the Ehime Maru," Waddle said.

"None of my crew members should be accountable or responsible for that accident."

Navy officials have not announced a decision on whether Lt. Michael Coen, who was the officer of the deck at the time of the incident, will get immunity.
