How is evidence challenged by Georgia criminal defense attorneys?
Challenging evidence in a Georgia criminal case can take several forms, each targeting a different aspect of how evidence is obtained, admitted, or interpreted. Because evidence reaches a jury only if it satisfies legal requirements, these challenges operate at distinct points in a case.
One avenue concerns how evidence was obtained. The exclusionary remedy under O.C.G.A. 17-5-30 allows evidence flowing from an unlawful search or seizure to be kept out of trial, which places the legality of law enforcement’s methods at the center of many challenges. A favorable ruling here can deprive the prosecution of material it intended to use.
Another avenue concerns admissibility. Before a jury may consider an item, it must clear thresholds of relevance and authentication, with O.C.G.A. 24-9-901 requiring a showing that the item is genuinely what the offering party says it is. A motion in limine offers a way to obtain an advance ruling on whether specific material reaches the jury at all.
The reliability and weight of evidence can also be contested. For scientific or forensic material, the underlying methods and the interpretation of results are open to examination, and where an item is capable of degrading or being substituted, its custodial history becomes relevant. Cross-examination supplies a further means of testing whatever evidence reaches trial.
Challenging evidence operates across the points where evidence is gathered, admitted, and weighed, with different tools suited to each. The aspect of the evidence at issue dictates the tool: a suppression motion for an unlawful search, an authentication or relevance objection for admissibility, and cross-examination or expert scrutiny for reliability.
