Martínez de Hoz & Rueda > The Legal 500 Rankings
Oil and gas Tier 1
For many, Martínez de Hoz & Rueda is ‘the best oil and gas firm in Argentina’. The comprehensive practice shines in all quarters of the hydrocarbons market, from exploration and production, through to transportation, distribution and marketing. Sources highlight the firm as ‘phenomenal in energy transactions’, where it is routinely called upon by oil-and-gas majors to advise on M&A, bidding rounds, joint ventures and financing matters. On the exploration side, it is advising ExxonMobil, Equinor Argentina and Mitsui on the development of their respective hydrocarbons’ businesses in Argentina, while on the infrastructure front, it is currently advising on several pipeline projects. It is also known for its formidable weight in the arbitration space and it frequently represents international oil companies in complex investment disputes and commercial arbitrations. José Martínez de Hoz co-heads the energy group — he also leads the arbitration practice — and is widely revered for his first-class experience and market profile. Energy department co-head Pablo Rueda is also highly regarded for his broad oil-and-gas expertise, which spans transactional, regulatory and environmental matters. The group also includes up-and-coming energy specialist Tomás Lanardonne.

Dispute resolution Tier 2
Few firms can match Martínez de Hoz & Rueda’s disputes offering in the energy space. The firm remains the first choice for domestic and foreign oil and gas companies looking to pursue litigation or arbitration mechanisms in Argentina, as testified by its recent work for ExxonMobil, Chevron and Wintershall Energía. Outside of the energy industry, the group’s first-class arbitration practice is also a big draw for telecoms, construction and financial services clients looking to conduct domestic, international or investment arbitration cases. Founding partner José Martínez de Hoz is widely recognised as a doyen of the Argentine arbitration bar and is particularly sought after for energy-related cases. Francisco Amallo, who co-heads the litigation and arbitration practice alongside Martinez de Hoz, is an increasingly prominent up-and-coming disputes specialist.
