If you think you have been discriminated against, you have the right to complain to different state institutions. You must choose the relevant state institution, applicable to your situation.
There are several state institutions in Ukraine that may take action in cases of discrimination. You can generally choose the relevant state institution depending on the field in which you have experienced discrimination.

Ombudsman
The Ombudsman is in charge of implementing the principle of equality and non-discrimination.
