The Indonesian Constitution mandates that Regional Head Elections be conducted
democratically. Through the Law on Regional Head Elections, democracy as
mandated by the constitution is defined as the way elections are conducted directly
and democratically. Democracy according to Robert A. Dahl's theory includes two
main elements, namely the level of participation and competition. The existence of
a single candidate in the Regional Head Election continues to increase every year
it is held. The purpose of this study is to determine and analyze the constitutionality
of a single candidate in the Regional Head Election and its consequences for the
realization of democracy in Indonesia. The type of research used is normative legal
research using primary legal materials and secondary legal materials. The data is
analyzed qualitatively. The results showed that a single candidate in the Regional
Head Election is constitutionally valid because it is in line with the constitution
which mandates democratic elections based on democratic measures according to
Robert A. Dahl's theory which includes the level of competition and participation
even though it is less perfectly realized. A single candidate in the Regional Head
Election has consequences for decreased voter participation, reduced democratic
quality, and the impact of further regional governance if led by an appointed
Regional Administrator due to an empty column wins or otherwise won by a single
candidate.
