The great variety of time limits for lodging complaints on potential mistakes on the voter list or the absence of registration prevents from drawing any trend. It is however interesting to underline that some countries provide very specific time limits, with clear beginning and end of the periods while a number of them provide for very broad periods of time for lodging such complaints, which is probably a wise approach. The countries allowing time limits till the eve of election day imply a very well organised electoral process and especially centralised voter registers, allowing almost last minute corrections without preventing the concerned voters from exercising their electoral rights.
