More than 100 Jewish attorneys and four religious organizations have filed an amicus brief siding with a death-row inmate who’s seeking a new trial amid allegations the judge referred to him using racist slurs about his Jewish heritage.

“The judicial system must purge itself of the resulting vestige of bias that undermines public confidence in the integrity and impartiality of our judiciary,” the brief said. “No individual should be executed without getting a fair trial untainted by considerations of race.”
