Public Procurement Law

Effective support for both contractors and contracting authorities

Public procurement is an area that demands precision, speed, and a thorough understanding of procedures.

At Siwek Gaczyński & Partners, we have provided comprehensive legal assistance in the field of Public Procurement Law (PPL) for years—supporting both bidders and contracting authorities.

We guide our Clients through every stage of the procurement process—from offer preparation and tender documentation analysis to representation before the National Appeal Chamber (KIO) and common courts.
We also support public entities in organizing tenders, including traditional procedures and public-private partnerships (PPP), making us one of the few firms with such broad experience in this field.

Our goal is not only to protect our Clients’ legal interests but above all, to help them secure contracts and eliminate unfair competition.
