MUST BE ABLE TO MAINTAIN A NEUTRAL/ANONONIMOUS STATUS DURING OR AFTER ELECTIONS
Electoral commissions in every country must be able to maintain a neutral status that means that they mustn't display impartiality or to be able to be bended to the will of opposition parties that hosts contestants the neutrality of electoral commission means that they do not support any body during general elections and every member that works in electoral commissions must not in any way be able to influence the outcome of elections that means that people who that means that people who works in the electoral commission must be able to stay away from things like political debate or attend political campaigns of either ruling party or contestant party so they must maintain a level of neutrality and anonymity in order for them not to be corrupt or show biasness.
MUST BE FREE OF FEDERAL, STATE OR LOCAL CONTROL
Every electoral commission in a country must not be funded by the federal state or local government else they would easily be coerced or forced to rig the electoral results so the salaries being paid to the people who work in the electoral commission should be a money funded and guaranteed by the constitution from the national budget alone that is the only way you will know that an electoral commission is capable to perform her duties and maintaining an upright and neutral status.
If these two things are done then it means that the status of the electoral commission in your country is top notch and does not support any party because they have no reason to since they cannot be controlled by federal state or local government and also maintain a neutral and anonymous status then they are incorruptible because they cannot be influenced by anyone
