2015 ORS 109.258¹
Effect of test results

A disputable presumption of paternity is created if one or more blood tests result in a cumulative paternity index of 99 or greater. If the court or administrator finds that the conclusions of all the experts, as disclosed by the evidence based upon the tests, are that the alleged father is not the father of the child, the question of paternity shall be resolved accordingly. If the experts disagree in their findings or conclusions, the question shall be submitted upon all the evidence. [1953 c.628 §4; 1985 c.671 §44b; 1999 c.80 §27]

Notes of Decisions

Although evidence of putative father's paternity index and its equivalents is highly probative, it also presents substantial danger of misleading trier of fact. Plemel v. Walter, 303 Or 262, 735 P2d 1209 (1987)

Evidence of putative father's paternity index should be admissible, but only subject to certain circumstances. Plemel v. Walter, 303 Or 262, 735 P2d 1209 (1987)
