#national legislation

The EU plans to hold a special meeting regarding the new US peace plan for Ukraine. This plan consists of 28 points and requires significant revisions. How will these international agreements affect the national legislation of Ukraine and what legal consequences may arise from their implementation?

I don't quite understand how the norms of international law and the national legislation of Ukraine on the provision of military support relate. Does Ukrainian legislation provide for the possibility of providing military assistance from other states in the event of a threat of war?

Do you believe that the use of foreign jurisprudence in domestic judicial practice can significantly influence the development of national legislation?

Do Polish authorities have the right to deport Ukrainian citizens for displaying the UPA flag during a concert in Warsaw, if this is considered a violation of Polish national law?
