We note, however, that since Rep. Act No. 8042 took effect on July 15, 1995, the Court had, in a catena of cases, applied the penal provisions in Section 6, including paragraph (m) thereof, and the last two paragraphs therein defining large scale illegal recruitment committed by officers and/or employees of recruitment agencies by themselves and in connivance with private individuals, and imposed the penalties provided in Section 7 thereof, including the penalty of life imprisonment. [22] The Informations therein were filed after preliminary investigations as provided for in Section 11 of Rep. Act No. 8042 and in venues as provided for in Section 9 of the said act. In People v. Chowdury,[23] we held that illegal recruitment is a crime of economic sabotage and must be enforced. In People v. Diaz,[24] we held that Rep. Act No. 8042 is but an amendment of the Labor Code of the Philippines and is not an ex-post facto law because it is not applied retroactively. In JMM Promotion and Management, Inc. v. Court of Appeals,[25] the issue of the extent of the police power of the State to regulate a business, profession or calling vis-à-vis the equal protection clause and the non-impairment clause of the Constitution were raised and we held, thus: A profession, trade or calling is a property right within the meaning of our constitutional guarantees. One cannot be deprived of the right to work and the right to make a living because these rights are property rights, the arbitrary and unwarranted deprivation of which normally constitutes an actionable wrong. Nevertheless, no right is absolute, and the proper regulation of a profession, calling, business or trade has always been upheld as a legitimate subject of a valid exercise of the police power by the state particularly when their conduct affects either the execution of legitimate governmental functions, the preservation of the State, the public health and welfare and public morals. According to the maxim, sic utere tuo ut alienum non laedas, it must of course be within the legitimate range of legislative action to define the mode and manner in which every one may so use his own property so as not to pose injury to himself or others. In any case, where the liberty curtailed affects at most the rights of property, the permissible scope of regulatory measures is certainly much wider. To pretend that licensing or accreditation requirements violates the due process clause is to ignore the settled practice, under the mantle of the police power, of regulating entry to the practice of various trades or professions. Professionals leaving for abroad are required to pass rigid written and practical exams before they are deemed fit to practice their trade. Seamen are required to take tests determining their seamanship. Locally, the Professional Regulation Commission has begun to require previously licensed doctors and other professionals to furnish documentary proof that they had either re-trained or had undertaken continuing education courses as a requirement for renewal of their licenses. It is not claimed that these requirements pose an unwarranted deprivation of
