'No law shall embrace more than one object, which shall be expressed in its title. No bill shall be altered or amended on its passage through either house so as to change its original purpose as determined by its total content and not alone by its title.'

'. . . The practice of bringing together into one bill subjects diverse in their nature, and having no necessary connection, with a view to combine in their favor the advocates of all, and thus secure the passage of several measures, no one of which could succeed upon its own merits, was one both corruptive of the legislator and dangerous to the state. It was scarcely more so, however, than another practice, also intended to be remedied by this provision, by which, through dexterous management, clauses were inserted in bills of which the titles gave no intimation, and their passage secured through legislative bodies whose members were not generally aware of their intention and effect. There was no design by this clause to embarrass legislation by making laws unnecessarily restrictive in their scope and operation, and thus multiplying their number, but the framers of the constitution meant to put an end to legislation of the vicious character referred to, which was little less than a fraud upon the public, and to require that in every case the proposed measure should stand upon its own merits, and that the legislature should be fairly notified of its design when required to pass upon it.

'While the legislature cannot delegate its power to make a law, it is well settled that it may make a law to become operative on the happening of a certain contingency or future event. 11 Am. Jur. 926, Sec. 216; 50 Am. Jur. 516, Sec. 497. The rule is thus clearly stated in 16 C.J.S., Constitutional Law, Sec. 141: 'It is a general rule that where an act is clothed with all the forms of law and is complete in and of itself, it is fairly within the scope of the legislative power to prescribe that it shall become operative only on the happening of some specified contingency, contingencies, or succession of contingencies. Such a statute lies dormant until called into active force by the existence of the conditions on which it is intended to operate."

'The universal rule is that, 'In the absence of constitutional or statutory provisions to the contrary, statutes may become effective on the happening of certain conditions or contingencies specified in the act, or implied therefrom.' 59 C. J. 1156, section 688; Town of San Mateo City v. State ex rel. Landis, 117 Fla. 546, 158 So. 112; Brown v City of Tampa, 149 Fla. 482, 6 So. 2d 287.

'The contingency may be the enactment or approaval of another enactment. Shehane v. Wimbish, 34 Ga. App. 608, 131 S.E. 104, text 105; Marr v.

'The contention that the Florida Revenue Act of 1949 is unconstitutional because 'integrated as it is with these two separate laws [it] embraces more than one subject without proper title' and therefore contravenes Section 16, Article III of the Florida Constitution, is without merit. Chapter 26319, Acts of Special Session of 1949, is a law which embraces but one subject and matters properly connected therewith. The fact that it is an act which was passed as part and parcel of a comprehensive tax program devised by the legislature in the exercise of its lawmaking power, makes it none the less a single law within the purview of Section 16, Article III of our Constitution. Indeed, the legislature could not perform its duties or measure up to its responsibilities if we were to give the narrow construction to Section 16, Article III of the Florida Constitution which is suggested by counsel for appellant. No single law could possibly be invented which would meet constitutional requirements and at the same time contain all of the essential features of a comprehensive legislative program on any subject which affects the general welfare so vitally as does taxation. The legislature pursued the only available course since its program necessarily involved a consideration of the tax structure not only of the State but also of its multiple political subdivisions and quasi-independent governmental units within its borders in the interest of the welfare of its citizens as a whole. A legislative program of such magnitude may necessarily involve several subjects before the ultimate end effect can be accomplished. It was essential, therefore, in enacting its program that the legislature provide a separate law for each subject with which it dealt. It had no alternative and it cannot be said that it violated Section 16, Article III of the Florida Constitution for actually it complied meticulously with the requirements of that constitutional provision.' [47 So 2d at 575]

'Appropriations may constitutionally be made contingent upon matters or events reasonably related to the subject of the appropriation, but may not be made to depend upon entirely unrelated events. For example, an appropriation to a university might be contingent upong the registration of a minimum number of students who could benefit from the appropriation or contingent upon the state revenues reaching a certain level. There is no constitutional impediment to an appropriation being made contingent upon another bill, reasonably related to the appropriation and where there is a direct and relative interdependence between them, becoming law.' [In Re Advisory Opinion To The Governor, 239 So 2d 1, 9 (Fla 1970); Emphasis added]

'It is also well settled that this constitutional provision (section 24 of article 4), requiring the subject of the act to be expressed in the title, must be liberally construed, and that all is required to be contained therein in order to meet the constitutional requirements is a reasonably intelligent reference to the subject to which the legislation is to be addressed. . . .

'The law is also well established that it is not necessary that the title of an act should embrace an abstract of its contents. It has always been the custom to state the subject of the bill in general terms with the fewest words, and the framers of the Constitution doubtless intended the Legislature to conform to that custom. Numerous provisions having a general object fairly indicated by the title may be united. When the general purpose is declared, the details provided for the accomplishment of that purpose will be regarded as necessary incidents. . . .

'. . . When a law goes into effect is no part of the act itself, and it is never the custom of the Legislature to place in the title the date when the act goes into effect. Hundreds of legislative enactments may be examined without the discovery of a single one in which the operative date is expressly mentioned in the title.'

'The veto power is a legislative function, although it is not affirmative and creative, but is strictly negative and destructive. It cannot be exercised by the executive except through constitutional grant. . . .' [Wood v State Administrative Board, 255 Mich 220, 224; 238 NW 16 (1931)]
