#entry ban

I am interested in whether there are mechanisms for appealing a foreign state's decision to ban entry to a Ukrainian citizen if this decision is considered discriminatory?

I am interested in whether Hungary has the right to deny entry to the commander of the Armed Forces of Ukraine, Robert Brovda, if he is a citizen of Ukraine and an ethnic Hungarian, and whether this does not contradict international law?

Hungary has banned entry to a Ukrainian military commander due to attacks on the Druzhba oil pipeline. Do I believe that such actions by Hungary are a violation of international law if they affect the activities of the Ukrainian military?
