Brian v. Johns
Petitioner Carol Brian initiated an action against respondent Frank T. Johns to establish paternity for her child, Sara, born March 4, 1973, and to secure child support. A court-ordered blood grouping test, conducted at the respondent's expense following an order on January 2, 1974, excluded Mr. Johns as the father. Unsatisfied with these results, the petitioner requested a second blood test, but the court denied this motion after reconsideration, citing respondent's opposition and the lack of statutory authority in Section 532 of the Family Court Act for ordering a second test over objection. The court ruled that the trial should proceed, requiring the respondent to present the performing doctor as a witness to explain the test's basis and procedure, allowing the petitioner to question its accuracy. The decision acknowledged a potential margin of error in such tests and affirmed the petitioner's opportunity to rebut the blood test evidence, as it is not the sole determinant of paternity.
