“When a Court puts a receiver in possession of property, the property comes under Court custody, the receiver being merely an officer or agent of the Court. Any obstruction or interference with the Court's possession sounds in contempt of that Court. Any legal action in respect of that property is in a sense such an interference and invites the contempt penalty of likely invalidation of the suit or other proceedings. But, if either before starting the action or during its continuance, the party takes the leave of the Court, the sin is absolved and the proceeding may continue to a conclusion on the merits. In the ordinary course, no Court is so prestige-conscious that it will stand in the way of a legitimate legal proceeding for redressal or relief against its receiver unless the action is totally meritless, frivolous or vexatious or otherwise vitiated by any sinister factor. Grant of leave is the rule, refusal the exception. After all, the Court is not, in the usual run of cases, affected by a litigation which settles the rights of parties and the receiver represents neither party, being an officer of the Court. For this reason, ordinarily the Court accords permission to sue, or to continue. The jurisdiction to grant leave is undoubted and inherent, but not based on black-letter law in the sense of enacted law. Any litigative disturbance of the Court's possession without its permission amounts to contempt of its authority; and the wages of contempt of Court in this jurisdiction may well be voidability of the whole proceeding. Equally clearly, prior permission of the Court appointing the receiver is not a condition precedent to the enforcement of the cause of action. Nor is it so grave a vice that later leave sought and got before the decree has been passed will not purge it. If, before the suit terminates, the relevant Court is moved and permission to sue or to prosecute further is granted, the requirement of law is fulfilled. Of course, failure to secure such leave till the end of the lis may prove fatal.
