For Chambers 2018, “Paloma Martínez Lage has broad expertise in cartel investigations, merger control and state aid. Clients appreciate that she is “dedicated, hard-working and pays a lot of attention to detail.” In its 2017 edition, Chambers defined her as a “Fantastic lawyer”, emphasizing that [she] is recognised for her experience in Brussels and hard-working approach. She has played a key part in some of the firm’s recent mandates, such as assisting clients with appeals against CNMC decisions and with cartel investigations”. Earlier editions said that “She is a very good lawyer. She has a very good knowledge, is hard-working, responsive and puts herself in clients’ shoes” (Chambers 2016).

Prior to joining the firm, Paloma worked as an in-house lawyer in the Corporate and Regulatory Affairs department of a mobile operator in Spain.

Paloma is a regular Competition Law lecturer in several postgraduate programmes, such as those of the Universidad CEU San Pablo, Universidad Carlos III and Club Español de la Energía.
