For 28 years, The Legal 500 has been analysing the capabilities of law firms across the world. The GC Powerlist is the latest publication from The Legal 500, turning its attention to the in-house function, and recognising those corporate counsel who are driving the legal business forward. The latest edition is the GC Powerlist: US Teams, which identifies an array of the most influential and innovative in-house teams working in the United States.
Our commitment to the in-house market is expanding, not only through the publication of the GC Powerlist Series, but also with our wide range of events, seminars, roundtables and legal updates. We have also launched GC Magazine, a quarterly title (free of charge to in-house counsel) that looks at the business of being an in-house lawyer, from a strategic, commercial and theoretical standpoint. We understand that the biggest issues facing in-house counsel today are, in fact, rarely legal issues. Our editor-in-chief, Catherine McGregor is now based in the United States and is travelling the length and breadth of the country to meet, interview, analyse and finally share the very best that the in-house market has to offer.
If you have feedback on the GC Powerlist: United States Teams, or wish to nominate other in-house individuals (either in US or global), please do get in touch at [email protected].
We hope that this listing will stimulate debate around the role of the in-house lawyer and help corporate counsel with possible improvements and efficiencies in running their departments.

Known as the ‘Pacto por México’, the package of structural reforms adopted by the current administration upon its election in 2012 has already helped bring more investment to Mexico. While it remains necessary to fully employ the national budget so as to create new jobs and further grow employment, major structural measures have already been legislated by Enrique Peña Nieto’s government and these will effect competition, energy, finance, labor, infrastructure, telecommunications, amparo law (a constitutional appeal), private data protection, public private partnerships, anticorruption, education, transparency and tax matters. Significantly, implementation has already begun. These structural reforms have been rolled out at a time when Mexico –like other jurisdictions- is enduring a notable reduction in oil prices, but this has had only a limited impact on global oil companies’ interest in Mexico’s offshore hydrocarbons potential, since the major oil-and-gas players are aware that such projects generally require years to develop and can provide returns for decades. According to the OECD, full implementation of the reform package in the short term is crucial to the country’s reaping the benefits that will accrue from a strong and sustainable recovery, and could add as much as one percentage point to the annual per capita growth trend of Mexico’s GDP.
Each of the reforms noted above, address the key issues and challenges in their respective sectors. The Mexican economy currently ranks as the world’s 11th largest and the country is also the fourth largest exporter of automobiles and manufactures the vast majority of flat screen televisions sold in the United States. In fact, Mexico exports more manufactured products than the rest of Latin America combined. Many US law firms have implemented or considered the hire of individuals or groups with significant business activity, opening offices in Mexico from where they can better serve their clients’ requirements or deliver services at a lower price. This scenario presents a unique opportunity not only to grow the services local firms provide to existing clients but also to compete for and acquire new clients.
On the other hand, the role of the in-house lawyer is crucially important since they manage the legal risks associated with the business and legal issues involved in all decisions by management. Moreover, in-house lawyers have to respond to increasing pressure on legal costs, responding proactively with initiatives for cost reduction and identifying appropriate benchmarks to permit the measuring of efficiency. When making the transition from private practice to an in-house role, most lawyers move from a specialist background to a more generalist role with responsibility for areas in which they have markedly less experience. This potentially opens huge areas of opportunity for them, since in-house lawyers who demonstrate the ability to make commercial decisions find it easy to connect with the (internal) business teams and will further a company’s ability to make sound strategic choices based on analysis that combines both legal and commercial factors.
In this regard, relationships between in-house lawyers and external lawyers are becoming increasingly important. The successful appointment of preferred legal advisors and the development of a close working relationship with a law firm can be a significant opportunity for in-house legal teams and can help save both time and money.

On 26 March, Legal 500 partnered with Portuguese law firm PLMJ to bring its renewed sustainability‑focused conference series to Lisbon with the ESG Forum: Portugal 2026. The half‑day event gathered senior leaders from the legal, financial, energy and sustainability spheres for a concentrated programme hosted at PLMJ’s offices. Throughout the sessions, speakers explored the regulatory, governance and enforcement forces reshaping ESG strategy in Portugal, offering a clear cross‑sector perspective on how organisations are adapting to an increasingly complex and fast‑moving landscape.
The event opened with some welcome remarks from Legal 500 editor Francisco Castro, who emphasised the value of events that bring the in‑house community together to learn, exchange experiences and build meaningful professional networks. In his welcome address, he highlighted the growing complexity of ESG obligations across Europe and the increasing pressure on organisations to adopt integrated, business‑wide approaches to compliance, risk management and strategic planning. By underscoring the need for practical, grounded discussion rather than abstract theory, he set the tone for a programme designed to deliver actionable insight and foster collaboration among practitioners navigating a rapidly evolving ESG landscape.
Followed an opening brief delivered by PLMJ’s Managing Partner, Bruno Ferreira, who provided a concise yet comprehensive overview of the ESG priorities defining Portugal in 2026. He outlined the expanding influence of EU regulatory frameworks on corporate reporting, due diligence and governance, noting how these requirements are reshaping expectations around data quality, transparency and accountability. His remarks positioned ESG not as a peripheral concern but as a central driver of corporate behaviour, capital flows and long‑term competitiveness in the Portuguese market.
The first panel, moderated by João Marques Mendes, Partner at PLMJ and joined by Cláudia Teixeira de Almeida of Banco BPI, Nuno Moraes Bastos of GALP and Diogo Graça of REN, explored how corporate governance and sustainable finance are shaping Portugal’s energy transition. The discussion examined how boards and executive teams are adapting oversight structures to manage transition‑related risks and how legal, compliance, sustainability and procurement functions are increasingly intertwined in project governance. Panellists described the growing influence of financing structures on project execution, noting that lenders’ expectations around ESG metrics, contractor performance and transparency now shape governance decisions from the earliest stages. They also addressed the operational constraints that continue to challenge Portugal’s transition ambitions, including permitting timelines, grid capacity limitations and delivery risk. While acknowledging the complexity of EU‑level frameworks, speakers emphasised that these standards also present strategic opportunities to harmonise practices, unlock investment and strengthen Portugal’s competitive position in the energy transition.
Following a short break, the second panel turned to litigation, liability and the emerging enforcement era surrounding sustainability claims. Moderated by Raquel Azevedo, Partner at PLMJ and featuring contributions from Carla Góis Coelho of PLMJ, Carlos Martins Ferreira of Jerónimo Martins, Filipa Rodrigues Carmona of Caixa Geral de Depósitos and Céline da Graça Pires of NOVA, the session examined the rapid rise of ESG‑driven disputes, investigations and regulatory actions. Panellists discussed the typical trigger points for scrutiny, ranging from sustainability reports and corporate websites to marketing materials and investor presentations, and highlighted how these touchpoints are increasingly tested by regulators, competitors, consumers and NGOs. They analysed recent case law developments and their implications for Portuguese organisations, noting the emergence of more stringent evidentiary standards around disclosures and due‑diligence obligations. The panel concluded that sustainability claims can no longer be treated as aspirational messaging; they now carry the weight of binding legal obligations, requiring more rigorous internal validation and cross‑functional coordination.
The forum concluded with closing remarks from Francisco Castro, after which attendees were invited to continue their conversations over a light lunch, providing a relaxed setting to deepen connections and reflect on the themes explored throughout the morning.
Legal 500 extends its thanks to PLMJ for its collaboration in bringing this conference format to Portugal’s in‑house legal community. The team looks forward to returning soon for the launch event of this year’s GC Powerlist: Portugal.
