IV. General Practice of Forensic Metrology
A. No services shall be rendered on a contingency fee basis.
B. It shall be regarded as ethical for the examiner/expert to reexamine evidence and metrology data previously submitted to or examined by another. Where a difference of opinion arises, however, as to the significance of the evidence, analytical results, spatial metrology gathered or software applied, it is in the interest of the profession that every effort is made by both examiners/experts to resolve their conflict before the case goes to trial.
C. Generally, the principle of "attorney/client" relationship is considered to apply to work of a physical evidence consultant except in a situation where a miscarriage of justice might occur. Justice should be the guiding principle.
D. It shall be ethical for an examiner/expert to serve an attorney in an advisory capacity regarding the interrogation of another expert who may be presenting testimony. This service must be performed in good faith and not maliciously. Its purpose is to prevent incompetent testimony, not to thwart justice.
