Noted for its deep knowledge of the public regulatory frameworks at the municipal, provincial and federal levels, Beccar Varela assists domestic and international companies with the full range of public law matters across the banking, agribusiness, life sciences, utilities, natural resources, infrastructure, construction, and telecoms sectors. Key areas of expertise include public procurement and bids for major projects, public works and infrastructure concessions, as well as public-private partnerships (PPPs), government contracts and transactions involving highly regulated sectors. The department is under the joint leadership of administrative law specialist Oscar Aguilar Valdez, who advises on public procurement, infrastructure concessions and PPPs, and Juan Antonio Stupenengo, an expert in constitutional, administrative, and regulatory law with extensive experience in public law litigation. Additional support is offered by senior associates Juan Pablo Perrino and Santiago Barbarán; Perrino handles contentious and non-contentious public law matters, while Barbarán stands out for his expertise in public procurement, administrative contracts, PPPs and public services regulations. The team has been further strengthened by the hire of Jimena Vega Olmos from Martínez de Hoz & Rueda; her caseload takes in public law matters as part of a broader electricity and projects practice – effective as of July 2025. Since publication, Perrino has been raised to the partnership - effective as of November 2025.
