# Legal Expert Was Barred From Opining on Good Time Credits

Posted on December 3, 2025 by Expert Witness Profiler

This litigation arises from Plaintiff Raymond Flanks’ (“Plaintiff”) wrongful conviction for first-degree murder in 1985. Plaintiff alleged that the Orleans Parish District Attorney’s Office (“OPDA”) secured his wrongful conviction in violation of his constitutional rights by withholding material exculpatory evidence.

Plaintiff retained [Robert Lancaster](https://expertwitnessprofiler.com/expert-witness/Robert-Lancaster/1569562), a lawyer, as an expert in Louisiana parole and pardon law.

Lancaster’s opinions concern when Plaintiff would have been released from prison on his sentence for armed robbery if he had not also been convicted of first-degree murder. Defendants contended that Lancaster’s testimony should be excluded because his expert report does not show that his opinions are reliably based on his experience or on the evidence in this case.
