Disqualified (as witnesses/participants) are: close in-laws and accomplices; the interested petitioner, the creditor, the holder/custodian (with a stake), and an enemy; as well as those bearing marks of punishment or disgrace. The earlier-mentioned categories are also non-justiciable (not fit to be proceeded with in court).
The court must filter testimony by conflict-of-interest and character/credibility indicators to reduce collusion, vendetta-driven claims, and fabricated evidence.
