La. Stat. tit. 33 § 2412
The director shall, subject to the rules, determine the qualifications for admission to any test. Subject to limitations as to age and other requirements and qualifications fixed by the rules in the interests of the service, admission to tests shall be open to all persons who possess the required qualifications and may be lawfully appointed to a position in the class for which a list is to be established. The director, subject to the rules, may reject the application of any person for admission to tests of fitness or refuse to test any applicant, or may cancel the eligibility of any eligible on any employment list, who is found to lack any of the qualifications prescribed as requirements for admission to the tests for the class for which he has applied, or who is physically unfit to perform effectively the duties of a position of the class, or who is addicted to the habitual use of drugs or intoxicating liquors to excess, or who has been adjudged guilty of a crime involving moral turpitude or infamous or notoriously disgraceful conduct, or who has been dismissed from the public service for delinquency or misconduct, or who has made a false statement of any material fact or has practiced or attempted to practice deception or fraud in his application or in his tests or otherwise in securing eligibility for appointment or attempting so to do. Any such facts shall also be considered cause for removal of any employee.
The director shall reject any application filed after the time fixed for closing receipt of applications as announced in the public notice of the tests, or after a specified number of applications, announced in the public notice of the tests, has been received.

Such laborers and workers may be selected and appointed by the appointing authority under such conditions and in accordance with such rules and regulations as the commission may from time to time adopt.
