[IND] In legal doctrine, attention is drawn to the relationship between instruments of direct democracy and the signature requirement, because the latter may block the  activity  ofcitizens. Therefore, this paper  focuses on signature requirements of local citizen’ initiatives (LCI), which is also analyzed  from  the  perspective of the principle of equality. We identify: the legal threshold of support (LTS) and the actual threshold of support (ATS). The legal threshold is construed as the statutory requirement of support (quantified or specified as a percentage), whereas the actual threshold of support is the quotient of the number of signatures required and the total number of residents in a given district. With  respect  to  the LCI, a district is an area of a municipality, poviat and voivodship. The ATS is an indicator used by us to study the principle of equality.
