Ondřej is a co-founder of Bříza & Trubač Attorneys at Law. In his practice, he focuses on a wide scope of legal services, in particular on the complex topic of tax proceedings and client's representation before tax administrators, including their consequent representation before administrative courts. Furthermore, in his practice he deals with administrative law in general as well as with the newly developing sub-area of criminal law – the criminal tax law and thereto connected issue of active repentance in the context of criminal liability of legal entities. He also provides counselling in the area of compliance to companies. On a regular basis he gives presentations and contributes to professional publications and other periodicals. Before the establishment of Bříza & Trubač he worked for almost 4 years in the largest Czech law firm and before that in leading advisory firms.


Ondřej has experience with client's representation in the tax proceedings, in particular during tax controls (he is the co-author of a successful publication titled Defence Against Tax Inspection) and by means of consequent actions before administrative courts against the tax administrator's decisions, in disputes often concerning dozens of million Czech crowns. Before administrative courts he also dealt with different administrative actions from the customs law area. In connection with the Act on Criminal Liability of Legal Entities coming into force in the Czech Republic he dealt with the implementation of corresponding provisions into the internal rules of companies.
