The immigration status of a Mexican native who is suing over lost wages in a workplace injury case should not be considered at trial because it can cause unfair prejudice, the Indiana Supreme Court has ruled.

The state's high court reversed a lower court ruling that the immigration status of Noe Escamilla was admissible in his lawsuit against an Indianapolis construction company. Escamilla, who entered the U.S. illegally from Mexico with his parents at age 15, married a U.S. citizen and has three children who are also American citizens, his attorney has said.

"Indiana's tort trials should be about making injured parties whole — not about federal immigration policies and laws," the high court said in a 5-0 ruling written by Chief Justice Loretta Rush and issued Thursday.

Escamilla sued Shiel Sexton Co. Inc. for lost future wages after he slipped on ice in 2010 and severely injured his back while helping to lift a heavy masonry capstone at Wabash College in Crawfordsville. Court documents say a doctor found Escamilla's injury left him unable to lift more than 20 pounds, effectively ending his career as a masonry laborer.

Because Escamilla is a lawful resident of Mexico, Shiel Sexton argued that any lost wages he is able to claim should be based on the rate of pay available in Mexico, and not U.S. wages. A Montgomery County trial court ruled in Shiel Sexton's favor, finding that two witnesses who reviewed Escamilla's U.S. tax returns could not testify about his lost earnings and that his immigration status could be entered as evidence.
