MIAMI (AP) – Four people who say they were harmed by pollution from Carnival Corp. cruise ships are seeking status as victims with rights to review a recent settlement.

Three Alaskans and one Bahamian have asked the 11th U.S. Circuit Court of Appeals to grant them status under the federal Crime Victims’ Rights Act. A Miami federal judge earlier this month rejected their claim before approving a settlement between Carnival and the Justice Department that included a $20 million penalty.

Carnival’s CEO admitted in court the world’s largest cruise line had violated probation terms from a 2016 criminal settlement over pollution that included a $40 million fine.

The four people who filed Monday’s appeal say they should have the right to review and participate in this newest settlement, which they consider flawed.
