Practice Groups

Traditional Values, Modern Thinking.

Our practice remains steeped in traditional values that have guided a century of law practice. While we have earned our reputation for professionalism and excellence, we also take pride in being “cutting edge.” We apply the latest legal and “out-of-the-box” thinking to a client’s problem, approaching it creatively, in a multi-disciplinary manner. This is due in large part to the fact that we hire and train lawyers not only on the basis of their excellent academic credentials from the finest schools (several of our lawyers have postgraduate degrees from foreign universities) but also on their ability to formulate innovative, unconventional solutions to legal problems. It is no surprise that many of our law firm’s alumni have gone on to contribute to the development of Philippine law, jurisprudence and politics, as legislators, cabinet secretaries, founders of new law firms, and Justices of the Supreme Court.

LABOR & EMPLOYMENT

SRMO is widely regarded as a titan in Philippine Labor and Employment law, a reputation built on over a century of representing management in the country’s most significant industrial relations disputes. The practice is renowned for its comprehensive approach, covering everything from day-to-day advisory to high-stakes litigation and collective bargaining, strike contingency, strike handling, labor litigation arising from termination, wage claims, unfair labor practice acts, and other employer-employee disputes, both trial and appellate, assumption-of-jurisdiction cases, compulsory and voluntary arbitration, and certification election proceedings. Our lawyers advise corporate clients on labor standards, occupational health and safety, and labor relations matter.

We can also secure rulings on national and local tax issues. Our lawyers handle tax assessments involving national and local taxes before the BIR, BOC, and various LGUs, and tax litigation cases before the trial courts, Court of Tax Appeals, and the Supreme Court.

IMMIGRATION

SRMO handles all types of emigration and immigration regulatory issues. SRMO’S Immigration Law practice group and the litigation department have handled many citizenship and naturalization matters. The most notable is the 1999 case which involved dual citizenship status and its effect on a political candidate’s qualifications for public office. The Supreme Court agreed with the firm’s legal argument that the Constitution proscribed “dual allegiance” and not dual citizenship per se.
