In any case, it is generally agreed that signature requirements should not be too high. The Code of Good Practice in Electoral Matters stipulates that a maximum of 1% signature requirement in relation to the electorate of the national or constituency level where elections are held should not be exceeded (CDL-AD(2002)023rev2.cor, part I. 1.3 ii). In several elections, the required number of signatures was relatively high, sometimes even surpassing the recommended maximum of 1%. In Montenegro, for instance, political parties and citizens’ groups nominating presidential candidates had to collect supporting signatures from at least 1.5% of the registered voters.
