Okla. Stat. tit. 58, § 58-235: Citation on suspension - Revocation of letters

When such suspension is made, notice thereof must be given to

the executor or administrator, and he must be cited to appear and

show cause why his letters should not be revoked. If he fail to

appear in obedience to the citation, or, if appearing, the court is

satisfied there exists cause for his removal, his letters must be

revoked, and letters of administration granted anew as the case may

require.
