The group is well known for its energy prowess and has strong expertise in project finance, trade finance and debt capital markets transactions for key clients such as Axion Energy Argentina, BNP Paribas and IFC. José Martínez de Hoz (n) and Martin Lepiane jointly lead the practice.

Martínez de Hoz & Rueda

Despite being a new firm Martínez de Hoz & Rueda’s sizeable four-partner dispute resolution practice fields some of the most experienced names in the market. In particular, department co-head José Alfredo Martínez de Hoz Jr is considered by many as ‘second-to-none for energy arbitration’; he recently represented YPF in a settlement agreement connected to a $1.6bn ICC arbitration initiated by a Brazilian natural gas importer, a Brazilian power generator and an Argentine natural gas transportation company. Martínez de Hoz also acts as an arbitrator and was recently appointed by América Móvil to arbitrate its $1.1bn ICSID investment dispute against Colombia. Elsewhere Francisco Amallo, who co-leads the practice, represented the International Basketball Federation in a dispute between the Peruvian Basketball Federation and the Peruvian Sports Institute. Jimena Vega Olmos and Juan Cruz Azzarri are also noted for their strong administrative law expertise.

Martínez de Hoz & Rueda

Martínez de Hoz & Rueda's oil and gas practice, which transferred in its entirety from the former Pérez Alati, Grondona, Benites, Arntsen & Martínez De Hoz, Jr, ranks among the market leaders due to its broad and deep coverage of the hydrocarbons area. The firm’s senior firepower in energy arbitration is a key draw, with José Alfredo Martínez de Hoz Jr highly sought after for his impressive track record in some of Argentina’s most high-stakes oil and gas disputes; he recently represented YPF in an ICC arbitration filed by a natural gas importer and a natural gas transportation company, which eventually settled for $60m – less than 5% of the original $1.5bn claim. The department also houses formidable transactional expertise and Martínez de Hoz Jr led the firm’s recent advice to Trafigura on the $145m acquisition of the majority of the downstream business of Pampa Energía. The practice group also benefits from the expertise of senior specialist Pablo Rueda, Neuquén office managing partner Tomás Lanardonne and Juan Cruz Azzarri.
