International arbitration proceedings give rise to a variety of choice-of-law issues, particularly when you add the increasing implementation of digital technologies. The success of the economic collaboration between the counterparties of various jurisdictions depends on the choice-of-law by the parties in dispute. This article focuses on how to properly choose the applicable law in arbitrations for international commercial disputes in the Republic of Panama, adding the particularities of the increasing use of digital technologies. The author explores the nuances and specificities when parties have expressly chosen an applicable law to the dispute and the legal reasoning and theories behind properly selecting the law applicable when the choice-of-law by the parties is absent, considering different approaches such as conflict-of-law rules, the closest connection test, the cumulative method, international conventions, and transnational principles of laws. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
