WASHINGTON, Nov 13 (Reuters) - Families of some victims

of two fatal Boeing 737 MAX plane crashes that killed 346

people asked a U.S. appeals court on Thursday to reverse a

decision by a judge to approve a request by the Justice

Department to dismiss a criminal case against the planemaker.

Judge Reed O'Connor, of U.S. District Court in Fort Worth,

Texas, on November 6 approved the Justice Department's request,

but harshly criticized the government's decision and said he

disagreed that dismissing the case was in the public interest.

The families asked the 5th Circuit Court to reverse his

decision, saying the Justice Department violated their rights as

crime victims when it negotiated a deal with Boeing ( BA ).
