WALDOBORO, Maine — A former waitress at Moody’s Diner has filed a federal lawsuit that accuses the owner of the iconic Maine restaurant of discriminating against her for not adhering to his religious beliefs.

The lawsuit on behalf of Allina Diaz of Waldoboro was filed Monday in U.S. District Court in Portland.

Diaz states in the lawsuit she was discriminated against, harassed and threatened with being fired for more than a year because she was not adhering to the religious beliefs held by her employer, Dan Beck.

Robert Brooks, the attorney for Moody’s, issued a statement Tuesday.

“Although Moody’s Diner has not yet been served with the complaint, we understand that Ms. Diaz is making the same allegations that were the subject of prior media reports,” Brooks wrote. “Moody’s Diner will continue to defend itself against Ms. Diaz’s allegations and maintains that it never subjected Ms. Diaz to any form of religious discrimination or retaliation. Moody’s Diner is committed to providing a workplace free of any type of illegal discrimination. We are confident that once the court considers all the facts, the court will reject Ms. Diaz’s claims.”

The lawsuit comes fewer than two months after the Maine Human Rights Commission denied a request from Gov. Paul LePage to reconsider its finding of sufficient evidence that Moody’s Diner discriminated against Diaz. The commission ruled in November 2014 that “reasonable grounds” existed to believe religious discrimination by Beck, a co-owner of the restaurant, resulted in a hostile work environment for Diaz. The commission also found reasonable grounds the restaurant had retaliated against her after she filed a complaint with the rights commission.

The governor also refused to allow the commission to transfer money to pay for temporary staffing after it refused his request to reconsider its decision.

The human rights agency staff tried to reach a settlement between Diaz and the restaurant after the commission’s ruling but did not succeed.

Diaz began working at Moody’s in 2002 and began dating Beck’s son in October 2012.

Diaz and Beck’s son no longer are in a relationship.

Beck is a devout Presbyterian. In the commission investigator’s report, Dion described several instances of Beck or his wife — who does not work at the restaurant — making disparaging comments to Diaz, including that she and Nathan Beck were “not following Jesus” by continuing their relationship and that the elder Becks did not support the relationship.

The federal lawsuit filed this week refers to an August 2013 meeting called by Beck with Diaz in which he told Diaz and his son that he did not want to have to see their lifestyle at work, and did not want to look at them every day when he knew the choices they were making. Beck said the lifestyle they displayed showed she did not believe in Christ, according to the lawsuit.

Beck also pointed out Diaz had not made a profession of faith, the lawsuit further stated.

Diaz refused to resign and afterward she said she was harassed and criticized for supposedly not meeting certain work standards no one else was required to meet.

The lawsuit seeks back pay and losses associated with lost benefits as well as punitive damages.
