‘Top-tier firm’ Marval, O'Farrell & Mairal impresses with its ‘deep and strong experience in all types of restructuring cases’. The well-balanced group acts for a broad range of creditors, shareholders, debtors and trustees — in both out-of-court restructurings and contentious bankruptcy cases. Senior of counsel MartĂ­n Campbell is widely regarded as a leading light; he teamed up with department head Fernando HernĂĄndez and finance specialists Ricardo Beller and Cecilia Mairal to advise the creditors’ committee on the implementation of Sociedad Comercial del Plata’s reorganisation plan. Moreover, in July 2019 the firm announced its absorbtion of the former Rivera & Asociados, long a noted disputes boutique and 'one of the market’s leading debtor shops’ for restructuring matters, particularly those with complex contentious proceedings. Founding partner Julio CĂ©sar Rivera was appointed as a “supplementary judge” (“conjuez”) of the National Supreme Court in 2018 and becomes an honorary partner at Marval. The team also includes litigations specialist Julio CĂ©sar Rivera (h), who also becomes a partner, and four associates. While it remains too early to evaluate the merger in full, early indications suggest this to be -in the words of one client- a 'win-win situation', boosting Marval's contentious and restrucuturing capabilities significantly. Other representative clients include Arla Foods Ingredients and Supercanal.

The practice, held up for its ‘unrivalled breadth and depth’, is led by heavyweight litigator Ricardo Ostrower, who brings to bear deep experience in complex, high-stakes disputes. Ostrower recently teamed up with Santiago Soria, and the oil and gas department, to represent Transportadora de Gas del Sur in an arbitration claim brought by Pan American Energy and Pan American Sur related to the performance of a long-term natural gas processing agreement. In another headline piece of litigation, Ostrower acted alongside the public law group to assist Cargill with its case against the Province of Chaco before the Federal Supreme Court arguing the unconstitutionality of certain provincial regulations impacting on its operations. Senior counsel MartĂ­n Campbell is ‘a remarkable lawyer’ and paired up with Facundo Viel Temperley to represent Credit Suisse as defendant in a class action concerning the Madoff fraud. Were the ‘seamless and joined-up team’, which also includes Rodrigo GarcĂ­a  and ElĂ­as Bestani, not formidable enough, in July 2019 the firm announced the absorbtion of 'outstanding disputes boutique' Rivera & Asociados, whom the Marval team had faced in the TGS-Pan American case. The merger adds signifcant firepower to the department, particularly in terms of arbitration: former managing partner Julio CĂ©sar Rivera is widely acclaimed as ‘the best arbitrator in Argentina’; he is also highly regarded for judicial restructuring cases and was appointed as a supplementary judge (“conjuez”) of the National Supreme Court in 2018. Julio CĂ©sar Rivera (h), who joins as a partner, is a ‘first-class litigator’. Incoming associates of note include arbitration specialist Laura Piedrahita Abella.
