Our class actions

In certain cases, our firm represents groups of individuals whose fundamental rights have been violated. Whether it involves unlawful detention, inappropriate conditions, or unjustified imprisonment, we put our expertise to work in collective actions to uphold everyone’s rights.

Expert and private investigator services

In certain cases, our firm calls upon experienced private investigators for surveillance, analysis, and witness preparation. When needed, we also engage qualified experts to challenge the prosecution’s evidence or produce counter-expert reports, thereby strengthening the defense strategy.
