A. No rule adopted on or after January 1, 1975, is valid unless adopted in substantial compliance with this Chapter. Each rule making agency shall file a certified copy of its rules with the Department of the State Register. No rule, whether adopted before, on, or after January 1, 1975, shall be effective, nor may it be enforced, unless it has been properly filed with the Department of the State Register. No rule, adopted on or after November 1, 1978, shall be effective, nor may it be enforced, unless prior to its adoption a report relative to the proposed rule change is submitted to the appropriate standing committee of the legislature or to the presiding officers of the respective houses as provided in R.S. 49:968. No rule, adopted on or after September 12, 1980, shall be effective, nor may it be enforced, unless the approved economic and fiscal impact statements, as provided in R.S. 49:953A, have been filed with the Department of State Register and published in the Louisiana Register. The inadvertent failure to mail notice and statements to persons making request for such mail notice, as provided in R.S. 49:953, shall not invalidate any rule adopted hereunder. A proceeding under R.S. 49:963 to contest any rule on the grounds of noncompliance with the procedures for adoption, as given in this Chapter, must be commenced within two years from the date upon which the rule became effective.

B. Each rule hereafter adopted shall be effective upon its publication in the Louisiana Register, said publication to be subsequent to the act of adoption, except that:

(1) If a later date is required by statute or specified in the rule, the later day is the effective date.

(2) Subject to applicable constitutional or statutory provisions, an emergency rule shall become effective on the date of its adoption, or on a date specified by the agency to be not more than sixty days future from the date of its adoption, provided written notice is given within five days of the date of adoption to the governor of Louisiana, the attorney general of Louisiana, the speaker of the House of Representatives, and the president of the Senate, and the Department of the State Register as provided in R.S. 49:953(B). Such emergency rule shall not remain in effect beyond the publication date of the Louisiana Register published in the month following the month in which the emergency rule is adopted, unless such rule and the reasons for adoption thereof are published in said issue; provided, however, that any emergency rule so published shall not be effective for a period longer than one hundred twenty days, except as provided by R.S. 49:967(D), but the adoption of an identical rule under Paragraphs (1), (2) and (3) of Subsection A of R.S. 49:953 is not precluded. The agency shall take appropriate measures to make emergency rules known to the persons who may be affected by them.
