Attorney-at-law Mari Past’s experience in the field of data protection, healthcare and competition law allows NOVE’s customers to prevent disputes. Mari focuses on the rules governing the activities of an entrepreneur and her timely and accurate advice can prevent a long and debilitating dispute.

In the wake of entry into force of the General Data Protection Regulation (GDPR), Mari conducts data protection audits and drafts impact assessments and privacy policies; helps keep record of processing activities and conclude data processing agreements between data controllers and processors; compiles and communicates internal data protection rules in companies; supplements employment and service provision agreements. One of the highlights of Mari’s work on data protection is advising the University of Tartu on the use of the Estonian Biobank, a database of genetic and health data of more than 200 000 people in Estonia, in research aimed at medical innovation.

In the heavily regulated sector of healthcare, Mari has a long track record of helping clients stay compliant with the complex regulatory framework. Mari has advised institutions of stationary and ambulatory medical treatment, international pharmaceutical corporations, merchants of medical devices, clinical research organisations and umbrella organisations in medical sector.

Mari has 10 years of experience in EU and Estonian competition law, advising clients in merger control, supply, sales and cooperation agreements, and on business restrictions of dominant undertakings.
