Політичні партії та їх взаємодія з інститутами політичної системи

The article characterizes political parties as a central element of the political system that ensures the representation of citizens’ interests, the formation of political elites, participation in shaping the state’s policy course, and the organization of public support for political decisions. It is substantiated that the effectiveness of parties is determined not only by their participation in elections, but also by their day to day interaction with institutions of power, within which societal demands are transformed into governance decisions. The main channels of such interaction are examined, focusing on the parliament, the government, the institution of the president or head of state, electoral administration, and the judicial system. It is shown that in parliament parties exercise influence through parliamentary factions and committees, coordination of legislative initiatives, coalition arrangements and opposition activity, as well as through instruments of government oversight that shape the political accountability of the executive branch. It is determined that at the governmental level parties form coalitions, secure support for program priorities through party discipline, staff executive structures, and bear political costs for the outcomes of public policy implementation. The role of parties in supporting candidates for the office of president or head of state and in building political legitimacy, which affects the stability of institutional interaction, is revealed. The importance of electoral bodies in ensuring equal political competition and in monitoring party financing and reporting during the electoral process is outlined. The place of courts and constitutional review in setting the legal limits of party activity, applying sanctions in cases of violations, and protecting democratic principles is described.
