Section 383. Revocation of certificate.

A certificate granted under this Part may be revoked for any of the following causes, namely:-- (a) that the proceedings to obtain the certificate were defective in substance; (b) that the certificate was obtained fraudulently by the making of a false suggestion, or by the concealment from the Court of something material to the case; (c) that the certificate was obtained by means of an untrue allegation of a fact essential in point of law to justify the grant thereof, though such allegation was made in ignorance or inadvertently; (d) that the certificate has become useless and inoperative through circumstances; (e) that a decree or order made by a competent Court in a suit or other proceeding with respect to effects comprising debts or securities specified in the certificate renders it proper that the certificate should be revoked.
