Peter Anderson, Carnival Corp.’s first-ever chief ethics and compliance officer and a central figure in leading the cruise line giant through its environmental compliance monitorship, has resigned.

Anderson’s departure from the company was effective Monday, Carnival stated in a regulatory filing. He informed the business May 13 of his decision.

Richard Brilliant, Carnival’s chief audit officer, will replace Anderson in the new role of chief risk and compliance officer.

Carnival’s five-year monitorship began in 2017, when the Department of Justice ordered subsidiary Princess Cruises to pay a record $40 million penalty for illegally dumping overboard oil-contaminated waste and falsifying official logs to conceal the discharges. Since then, the company has been penalized twice more for additional violations, including in 2019 ($20 million) and January ($1 million)

The term of the five-year probation was expected to end in April, though the case is still open. As recently as last month, the two sides disagreed over quarterly disclosures of waste discharge volumes.

“Accolades bestowed on (Carnival) at the close of probation were apparently premature,” the government wrote in court documents. “While touting its transparency and leadership, Carnival’s leadership now seeks to conceal information about the nature and extent of the company’s legal pollution.”

Judge Patricia Seitz of the U.S. District Court for the Southern District of Florida held a status conference with Carnival regarding the case on April 11; the transcript is set to be made public in July.

On April 14, Anderson signed off on an action plan at Carnival outlining next steps to be taken by its Incident Analysis Group and compliance department, which included the hiring of additional staff with investigative backgrounds.

The Carnival environmental compliance monitorship was highlighted in detail as part of a Compliance Week case study released in September 2020.

Anderson joined Carnival in August 2019, two months after it was fined the $20 million for its probation violations. He had previously been the head of the White Collar and Compliance Group at law firm Beveridge & Diamond and was initially engaged by Carnival to conduct a compliance program assessment. Anderson, a former federal prosecutor, also led the environmental compliance team on the Volkswagen monitorship for two years.

Brilliant served as Carnival’s chief audit officer since 2007, according to his LinkedIn profile. He joined the company in 2003.
