This appeal involves the constitutionality of a Tennessee statute dealing with the problem of rented premises unfit for human habitation. Chapter 139, Public Acts of 1973, codified at T.C.A. §§ 53— 5501 to 53-5507.
The statute applies only to tenants who pay rent of $50 per week or less. As a prerequisite to obtaining relief, the tenant must have paid to the landlord all sums due and owing and must deposit with the county court clerk one month’s rent. This security deposit is returned to the tenant if the premises are found to be unfit for habitation, but, if the complaint proves to be unfounded, the deposit is forfeited to the State for the *631use of the county agency to which the complaint was directed.
After a complaint has been filed, a building inspector inspects the premises and the landlord is given 30 days to correct any deficiency found. If the landlord does not effect adequate repairs within this period, the tenant makes rental payments to the county court clerk for the next six months. If the premises have not been made fit for habitation within six months, all the rent is forfeited by the landlord to the State for the use of the county agency.
Dennis Moore rented a house for $95 per month. Believing that this house did not meet minimum health standards, he attempted to file a complaint with the building inspector of Knox County, Tennessee, and sought to obtain an inspection of the premises. He contended that because of his poverty he was unable to pay the security deposit of one month’s rent as required by the statute. Inspection was refused without advance payment of the deposit as required by the statute.
Thereupon Moore filed this action in the District Court seeking a declaratory judgment that the statutory requirement for a security deposit is unconstitutional.
In an opinion published at 381 F.Supp. 587 (E.D.Tenn.1974), the District Court held the requirement for a security deposit to be invalid under Lindsey v. Normet, 405 U.S. 56, 92 S.Ct. 862, 31 L.Ed.2d 36 (1972), emphasizing that the effect of the statute is to require a complaining tenant to pay a double penalty for the privilege of making a complaint, i.e., by paying a month’s rent to the county court clerk and also a month’s rent to the landlord for the same month.
There has been no appeal from that part of the decision of the District Court holding unconstitutional the requirement that a tenant make a security deposit. The judgment of the District Court on this issue is final and the question is not before this court on appeal.
The District Court further pointed out that the Act does not apply to all tenants, but is restricted to those who pay $50 a week or less for rent, and concluded: “To permit certain tenants to invoke the benefits and protection of this statute and to deny the same to others, in the absence of any reasonable basis, offends the equal protection clause of the Fourteenth Amendment.” 381 F.Supp. at 591. We hold that there is a reasonable basis for limiting the application of the Act to tenants paying not more than $50 a week for rent. This is a matter of legislative classification. See Village of Belle Terre v. Boraas, 416 U.S. 1, 8 & n. 5, 94 S.Ct. 1536, 39 L.Ed.2d 797 (1974); Jefferson v. Hackney, 406 U.S. 535, 545-47, 92 S.Ct. 1724, 32 L.Ed.2d 285 (1972); Dandridge v. Williams, 397 U.S. 471, 484-87, 90 S.Ct. 1153, 25 L.Ed.2d 491 (1970); Williamson v. Lee Optical Co., 348 U.S. 483, 488 — 89, 75 S.Ct. 461, 99 L.Ed. 563 (1955).
Having found invalid both the security deposit requirement and the $50 rental classification, the District Court held the Act unconstitutional in its entirety. Since we have reversed on the classification issue, we believe that the doctrine of elision now can be applied, striking that part of the statute requiring the security deposit which was found to be invalid, and preserving the validity of the remainder of the legislation.
The statute as codified is made an appendix to this opinion, with the elided portions of T.C.A. §§ 53-5503 and 53-5506 set forth in the brackets.
The doctrine of elision is well established in Tennessee. Mayor and Aidermen v. Wilson, 212 Tenn. 55, 60, 367 S.W.2d 772 (1963); Scott v. Nashville Bridge Co., 143 Tenn. 86, 122-23, 223 S.W. 844 (1919).
Although the doctrine is not favored, Tennessee courts have applied it consistently to avoid defeat of apparent legislative intent in the enactment of a statute, where the statute upon its face discloses a fact situation that brings it within the rule. Davidson County v. Elrod, 191 Tenn. 109, 111, 232 S.W.2d 1 (1950).
*632When a statute contains one or more unconstitutional provisions, the obnoxious provisions will be eliminated and the statute sustained as to the rest, unless the invalid provisions are deemed so essential, and are so interwoven with others, that it cannot reasonably be presumed that the legislature intended the statute to operate otherwise than as a whole. Lindsay v. Allen, 112 Tenn. 637, 647, 82 S.W. 171 (1904).
Where an invalid provision is incidental and subordinate and can be stricken without impairing the efficacy of the act, this will be done. Kyle v. Marcom, 181 Tenn. 57, 71, 178 S.W.2d 618 (1944); Williams v. Mabry, 176 Tenn. 343, 347, 141 S.W.2d 481 (1940).
The statute contains the following severability clause:
SECTION 7. If any provision of this act or the application thereof to any person or circumstance is held invalid, such invalidity shall not affect other provisions or applications of the act which can be given effect without the invalid provision or application, and to that end the provisions of this act are declared to be severable. T.C.A. § 1 — 310 is as follows:
1-310. Severability of Code. — It is hereby declared that the sections, clauses, sentences and parts of the Tennessee Code are severable, are not matters of mutual essential inducement, and any of them shall be ex-scinded if the Code would otherwise be unconstitutional or ineffective. If any one or more sections, clauses, sentences or parts shall for any reason be questioned in any court, and shall be adjudged unconstitutional or invalid, such judgment shall not affect, impair or invalidate the remaining provisions thereof, but shall be confined in its operation to the specific provision or provisions so held unconstitutional or invalid, and the inapplicability or invalidity of any section, clause, sentence or part in any one or more instances shall not be taken to affect or prejudice in any way its applicability or validity in any other instance [C.Supp.1950, § 27.3; modified.]
A severability clause must be taken into account in determining the legislative purpose unless observance thereof would frustrate the dominant legislative intent. Donathan v. McMinn County, 187 Tenn. 220, 237-38, 213 S.W.2d 173 (1948); Gates v. Long, 172 Tenn. 471, 480-81, 113 S.W.2d 388 (1938) (opinion by Chief Justice Grafton Green).
If possible, it is the duty of the courts to give effect to a severability clause and to make an elision, so as not to invalidate an entire act. Carr v. State ex rel. Armour, 196 Tenn. 256, 260, 265 S.W.2d 556 (1954).
The action of the Tennessee Legislature that culminated in the enactment of Chapter 139, Public Acts of 1973, originated with House Joint Resolution No. 50 adopted May 28, 1971. This resolution is as follows:
HOUSE JOINT RESOLUTION NO. 50
A RESOLUTION directing the Legislative Council Committee to study the factors contributing to the expansion and perpetuation of slum conditions in the four major cities of Tennessee.
WHEREAS, the suburbs of our cities have burgeoned while the central cities decay so that people are living in a sea of social and economic decay while affluence is around them; and
WHEREAS, The impact of various housing programs have not stopped the growth of slums nor removed the environmental disorder of slums from the cities; and
WHEREAS, The news media have given coverage to the urban ills and have drawn attention to the mounting problems of the financial woes of cities, their decayed and dangerous streets, and their slums and the need to stimulate the regeneration of cities; and
WHEREAS, The cost of allowing our central cities to deteriorate physically to a point where government subsidies are required to renew large *633portions of them is an economic drain; and
WHEREAS, The elimination of contributing factors, whether governmental or private, to the development and growth of slums might spur the rehabilitation and lessen the need for urban renewal or other government actions; and
WHEREAS, It should be possible to live the “good life” in either the central city or suburbia; and
WHEREAS, New programs at state and local levels may be needed for the rehabilitation and preservation of our cities; now, therefore,
BE IT RESOLVED BY THE HOUSE OF REPRESENTATIVES OF THE EIGHTY-SEVENTH GENERAL ASSEMBLY OF THE STATE OF TENNESSEE, THE SENATE CONCURRING, That the Legislative Council Committee be directed to study the factors contributing to the expansion and perpetuation of slums and urban decay of the cities of Chattanooga, Knoxville, Memphis, and Nashville and the problems of rehabilitation and renovation of these urban areas and to recommend legislation that would lead to new programs at state and local levels to eliminate these factors and problems; and to report its findings and recommendations to the Eighty-Eighth General Assembly.
BE IT FURTHER RESOLVED, That the University of Tennessee, Tennessee State University, and Memphis State University be directed to cooperate in this study.
Research is one of the functions of the Legislative Council Committee. T.C.A. § 3-404. The appellate record in the present case does not contain a copy of the report of the study conducted by the Council pursuant to House Joint Resolution No. 50. The 1973 statute by its terms reflects a legislative intent to provide a procedure for the correction of violations of minimum health standards that render low-cost rental property unfit for human habitation.
We hold that the requirement for a security deposit of one month’s rent, which the District Court found to be invalid, is incidental and subordinate to the other provisions of the statute. The remainder of the statute can be given effect without the requirement for a security deposit. In the above-quoted severability clause the legislature has declared that if any provision of the Act be held invalid, such invalidity shall not affect other provisions of the Act that can be given effect. If possible, it is our obligation to construe the statute so as to accomplish the legislative intent.
Accordingly, we reverse the decision of the District Court holding the entire Act unconstitutional. We hold that the statute as set forth in the appendix of this opinion, with the bracketed language omitted, is a valid and constitutional Act. We elide from T.C.A. § 53 — 5503 the following:
and shall have deposited with the county clerk of the county in which the complaint is to be filed a sum equal to one (1) month’s rental which sum shall be: (1) returned to the tenant upon final determination that the rented premises fails to meet the said standards or (2) forfeited by the tenant to the state for the use of the county agency to whom the complaint was directed upon a final determination that the rented premises meets the said standards.
We elide from T.C.A. § 53 — 5506 the words “deposit and” and “not including said deposit.”
Reversed. Costs are taxed against the Commissioner of the Tennessee Department of Public Health in his official capacity.
