In the case of In Re David, 93 Phil 461 (1954), the act of being a legal consultant is a practice of law. To engage in the practice of law is to do any of those acts that are characteristics of the legal profession. As such, neither can he allow his name to appear in such pleading by itself or as a part of a firms name under the signature of another qualified lawyer as he is under suspension from the practice of law. Thus, he cannot do indirectly what the Constitution prohibits directly.
In Philippine Lawyers association vs Agrava, 105 Phil 173 (1959), the practice of law iss not limited to the conduct of cases or litigation in court. It embraces any activity in or out of court that requires the application of law, legal principles, practices or procedures and calls for the legal knowledge, training and experience. Moreover, only the Supreme Court has the exclusive and constitutional mandate (Art 8, Sec. 5(5))with respect to the admission to the practice of law in the Philippines. And, any member of the philippine Bar in good and regular standing may practice law anywhere and before any entity, whether judicial or quasi-judicial or administrative in the Philippines.
In the case of People vs Villanueva, 14 SCRA 109 (1965), practice of lawimplies the customary or habitual holding of oneself to the public as a lawyer and demanding compensation for his services. Moreover, private practice is more than an isolated appearance for it consist of frequent customary actions, a succession of acts of the same kind. It may, however, amount to practice of law in relation to the rule prohibiting some persons from engaging in the exercise of the legal profession (e.g all members of the judiciary, judges, President, Vice-president, etc.)
In Ulep vs Legal Clinic, 223 SCRA 378 (1993), the practice of law is not limited to the conduct of cases in court. It includes legal advise and counsel, as well as preparation of legal instruments and contracts by which legal rights are secured, although such matter may or may not be pending in a court. When a person participates in a trial and advertises himself as a lawyer, he is in the practice of law. One who confers with his clients, advises them as to their legal rights and then takes the business to an attorney and asks the latter to look after the case in court is also practicing law. Giving advice for compensation regarding the legal status and rights of another and the conduct with respect thereto constitutes a practice of law. And, the standards of the legal profession condemn the lawyer's advertisements of his talents. A lawyer cannot, without violating the ethics of his profession adevertise his talents or skill in a manner similar to a merchant selling his goods. The only exceptions are when he appears in a reputable law list and use of ordinary, simple professional card.
And, in the case of Cayetano vs Monsod, 21 SCRA 210 (1991), to engage in the practice of law is to perform those acts which are characteristics of the legal profession. Generally, to practice law is to give notice or render any kind of service, which devises or or services require the use, in any degree, of legal knowledge or skill. As such, Atty. Monsod's past work experiences as a lawyer-economist, lawyer-mangaer, lawyer-entrepreneur of industry, lawyer-negotiator of contracts, and a lawyer-legislator of both the rich and poor verily satisfy the constitutional requirement that he has been engaged in the practice of law for at least 10 years.
