Quandary of these coming Party Nominations

Political parties will have to nominate candidates by the 18th January 2012. Accordingly, nominations will depend on: 1. For political parties - signatures of people supporting the party from voters designated as valid for the March 4th elections. 2. For independent candidates for NA and Senate and all presidential candidates - on signatures as outlined in Article 99 (c) (i) & (ii) and Article 137 (1) (c) and (d) For this to happen, the voters register must be compiled, inspected and published. the period for doing this according to the Elections Act (which is the law in force) is 60 days from the designated last date of registration for voters wishing to participate in the 4th march elections, i.e. 60 days after 18th Dec 2012. This means that the official register, according to the law, will be ready by 18th February 2013. For a person to be nominated as a candidate or for the party lists (the nomination shall be presented to the IEBC at least 45 days before the elections, i.e 18th January 2013), they should be members of the political party by 4th January, and must have proof that they are registered voters. My question is: what voters roll do we use for the nomination of political parties? Or is there information that i do not have?
