How is precedence determined between two claimants to a foundling when both possess valid legal evidence (bayyinah)?

Primary text

If each claimant has proof, precedence is given to the one whose proof is chronologically earlier. The second claimant is superseded because the right was established for the other party before his claim arose. If the dates of their proofs are identical, or if both are general without dating, or if one is dated and the other is general, the proofs contradict each other.
