Missouri Revised Statutes Title XXXV. Civil Procedure and Limitations § 515.600. Judicial immunity--actions against receivers, when

1. A receiver appointed pursuant to sections 515.500 to 515.665, and the agents, attorneys, and employees of the receivership employed by the receiver pursuant to section 515.605 shall enjoy judicial immunity for acts and omissions arising out of and performed in connection with his or her official duties on behalf of the court and within the scope of his or her appointment.  A person other than a successor receiver duly appointed by the court does not have a right of action against a receiver under this section to recover property or the value thereof for or on behalf of the estate except as provided in subsection 2 of this section.  A successor receiver may recover only actual damages incurred by the receivership estate from a prior receiver.

2. A person, other than a successor receiver duly appointed by the court, shall not have the right to bring an action against a receiver or the agents, attorneys, and employees of the receivership employed by the receiver pursuant to section 515.605 for any act or omission while acting in the performance of their functions and duties in connection with the receivership unless such person first files a verified application with the appointing court requesting leave to bring such action and the court grants such application after notice and hearing.  The appointing court shall only approve the application to bring claims against the receiver under this section upon a prima facie showing by the person making such request that the receiver's actions are not protected by the grant of immunity set forth in subsection 1 of this section.  No other court apart from the appointing court shall have the authority to review or approve the application to bring claims against the receiver under this section.

3. If a person requests leave to bring claims under subsection 2 of this section and such leave is denied, the court shall grant judgment in favor of the receiver for the costs of the proceeding and reasonable attorney's fee if the court finds that the position of the person was not substantially justified.
