Offer of Proof; Preserving Error for Appellate Review under Rule 103(a) (2)
By: Houston Criminal Defense Attorney John Floyd and Paralegal Billy Sinclair
In a recent article (“False Forensics: An Attorney’s Worst Nightmare.” 05-01-09), we reported on the increasing problems associated with the specialized field of forensic science. Prestigious organizations and scientists are calling now for a National Institute of Forensic Science with strict standards and enforcement mechanisms set up to insure that only truthful and valid forensic evidence is used to convict criminal defendants. It was faulty forensic science and lack of professional standards that prompted a former Houston Police Department crime lab technician to testify falsely in the rape and robbery trial of Gary Alvin Richard in 1987. Richard was recently released from prison after serving 22 years on a life sentence for violent crimes he did not commit. He case marked the fourth criminal defendant wrongfully convicted in Harris County because HPD crime lab technicians either lied or misrepresented forensic evidence test results to produce criminal convictions for unethical county prosecutors.
In our “False Forensics” blog, we concluded by saying: “Because of all the recent revelations and developments in the forensic science system, criminal defense attorneys now have an increased responsibility to challenge all forensic evidence offered at a criminal trial; to demand the methods used for gathering, processing, and preservation of that evidence; and to request for discovery of all notes by any analysts testing the evidence. Defense attorneys can no longer take this evidence as ‘scientifically’ infallible. Not only must defense lawyers thoroughly cross-examine these pro-prosecution witnesses about testing methodology, they must also identify all the analysts and support personnel involved in the testing process. Finally, defense attorneys must press for disclosure of testing mistakes made by the testifying ‘expert’ as well as all other mistakes made by others in the crime lab for which he works. This information goes to the heart of ‘reliability’ of the expert testimony, an issue open to cross-examination in Texas criminals.”
A decision by the Texas Court of Criminal Appeals (“CCA”), Woodall v. State, issued on April 29, 2009 not only revised the manner in which expert testimony and evidence must be challenged but underscored the responsibility of defense counsel to properly object to this kind of testimony in order to preserve the issue for review. 1/ The Woodall case involved a DWI conviction obtained in Harrison County. The Sixth District Court of Appeals (“Sixth District”) had reversed his conviction on February 22, 2007. 2/ The Sixth District had seven other DWI cases pending before it at the time, all raising the same issue decided in the Woodall case. The Sixth District consolidated these seven cases and overturned the convictions in each on March 7, 2007. None of the seven cases were designated for publication. The CCA granted the state’s petition for discretionary review in all eight cases and consolidated them for one decision.
The issue upon which the Sixth District based its reversals involved the science associated with the Intoxilyzer 5000, a machine that tests samples of breath for alcohol content. The attorneys in all the cases, except for Woodall’s attorney, filed motions to cross-examine the State’s expert on the operation of the Intoxilyzer 5000 and each motion listed the following eight areas of concern about the internal workings of this breath testing machine: (more…)
