Work Department

Dispute Resolution, Public Law and Projects




Partner and co-founder of the firm Ariza y Marín, with specialization in tax legislation and university professor, with whom during his 12 years of experience he has developed his professional practice in the field of infrastructure projects, conflict resolution, crisis management and teaching. His services have been highlighted as timely, generating value to his clients, who recognize his ability to have a deep knowledge of the value production chain of his clients and the ability to generate strategic legal solutions.

During his professional practice, he has successfully advised infrastructure projects worth over one billion Colombian pesos (COP 1 billion), among which projects of high technical complexity and technological innovation stand out, such as the urban renewal of water and sewage networks in the cities of Medellin and Bogota, through trenchless technology systems, as well as strategic projects in terms of meeting social needs, such as the construction of water storage tanks that will guarantee the supply of water to the city of Buenaventura by solving a serious existing social problem. In both cases, he has understood the dynamics of these contracts and has successfully implemented solutions that have made the execution of these projects viable.

In the area of conflict resolution, he has focused his practice on arbitration, where he has successfully represented his clients both in arbitration tribunals and in appeals against arbitration awards. He has also participated in international tribunals and cross-border conflict resolutions, successfully reaching out-of-court settlement agreements and/or within the judicial process, highlighting the representation of an international consortium before the International Chamber of Commerce in the amount of USD 40 M, which ended in a settlement agreement and an arbitration tribunal derived from the construction of a hydroelectric project in which a high density polyethylene pipeline was used for the first time in Colombia in the water conveyance system, which is currently underway. He is currently part of a dispute resolution team preparing the initiation of an International Tribunal to settle disputes arising from a contract executed in Peru by a consortium of Colombian companies.

He has provided legal advice to companies in crisis situations, in important high profile cases, some of which have been covered by the national media, such as the CDO Group in disputes exceeding USD 50 M.

Very strong in the state-contracting niche‘, according to peers, Ariza & Marin is a highly specialised, eight-strong disputes firm, that is increasingly breaking out of its regional niche – indeed the firm, enters our national ranking for both projects and public law this year. Founded in 2009, it is particularly prominent in the projects segment related to highway concessions and, increasingly, energy projects; it is also active in relation to insurance, civil/state liability, and consumer law. With an LLM in public law and specialisations in tax and civil liability, Carolina Ariza has 13 years’ disputes experience; primarily focused on complex negotiations and high-impact legislation, she is currently preparing a case addressed to ANI seeking recognition of the damages incurred by the concessionaire for over-runs in the development of the 493km Transversal de Américas road project. Fellow founding-partner Camilo Marín focuses on insurance, civil responsibility, and public and private contracting; with 13 years’ disputes experience (primarily arbitration), he is currently representing Obras Civiles e Inmobiliarias (OCEISA) in a COP$13.4bn case brought by EPM seeking damages in relation to the cancelled Parques del Río Project in Medellín.. Marín also has niche expertise in crisis management. Also noted is key senior associate Nicolás López Ochoa, a public and private contracting specialist who handles administrative, consumer and commercial matters ranging from class actions to contractual disputes. And while Laura Castaño, who had joined the firm in January 2020, subsequently returned to Tamayo Jaramillo & Asociados as a partner, the firm has since hired Luis Felipe Estrada as associate-head of the insurance practice (and co-head of public law), from Sura Seguros; effective as of February 2021.
