What is the ruling on erroneous DNA paternity test results or falsified information resulting in the issuance of a court order proving paternity and which the court later found to be incorrect?

Islamic law exercises extreme caution in matters related to paternity. Consequently, it is only acceptable to rely on DNA paternity testing after taking extremely strict measures to prevent mistaken paternity and protect honor. The Islamic Fiqh Assembly of the Muslim World League issued in its sixth session held from 22-26/10/1422 AH (5-10/1/2002 AD) the following resolution: "DNA testing to trace lineage must be handled with utmost caution and confidentiality. It is not lawful to give it priority over maxims and proofs from Islamic law.” Accordingly, incorrect DNA paternity test results must be immediately corrected and the child must be traced to his/her legitimate father. The child becomes a [genetic] stranger to the wrong father.

And God Almighty knows best.
