The big majority of countries providing for short time limits concerning complaints lodged on refusal of candidate registration are in line with the Code of good practice in electoral matters, although the Code does not distinguish time limits duration between types of complaints. Time limits for both lodging and adjudicating a complaint should be as short as possible as a late registration of a candidate can reduce her or his campaign period. Denmark does not have administrative appeal mechanisms for candidate registration, at least in its electoral laws. It is not appropriate to leave more than five days, which is the case of seven countries among the 59 countries analysed, for challenging a refusal of registration. Once the refusal is notified, a shorter time frame should be enough for the candidate to collect the elements needed to prove the potential illegality of such a refusal and lodge the complaint.
