Also integral to the team, Jorge Muratorio is particularly dedicated to contentious competition matters arising in relation to highly regulated markets and public service clients, as well as broader regulatory analyses. Senior associate Rebeca Fernández has a broad public law specialisation and plays a key role in preparing filings, submissions and broader defence strategies before the authorities.
