The Supreme Judicial Court today told Luis Melendez-Diaz his precedent-setting case in Boston came too late to help him try to clean his record of another drug conviction on the South Shore.
In 2009, the Supreme Court ruled Melendez-Diaz's right to confront his accusers had been violated in his 2001 conviction in Boston because his lawyer could not cross-examine the lab technician who signed a certificate that the substance found in the car in which he was a passenger was cocaine.
