Mississippi Code Title 7. Executive Department § 7-1-49

A commission shall issue to the examiner, vesting in him authority to do and perform the duties for which he may be appointed. He shall have authority to issue subpoenas for witnesses whom he may wish to examine, administer oaths to them, and to compel their attendance; and shall have full authority to require officers whose books and accounts are being examined, and their deputies and clerks, to render him assistance and give him information needed in the prosecution of his investigations. The examiner shall have the same power to punish a witness who fails or refuses to attend and testify before him as conferred by law on justices of the peace; and an officer, his deputy or clerk, failing to give assistance or information to the examiner when required shall be punished as for a failure or refusal to perform official duty.
