Mr. Goldman’s client was on probation and submitted to a drug test. The result of the drug test was that Mr. Goldman’s client violated the terms of probation by using illegal drugs. These are notoriously difficult cases to win and can result in revocation of the probation and immediate imprisonment. At the hearing, the prosecutor had brought the lab technician to testify about the results of the drug test. However, Mr. Goldman chose to attack what is called in law the ‘chain of custody.’ Essentially, Mr. Goldman challenged the evidence that the sample being tested had actually come from Mr. Goldman’s client. Since the prosecutor couldn’t respond to Mr. Goldman’s adaptive move, the judge dismissed the allegation against Mr. Goldman’s client.
