It could be argued that if a person is entitled (competent) to decide on an issue, s/he can also annul his or her own decision (actus contrarius²⁶). This is related to the idea that a person who has a power can also do less than fully exert that power (qui potest majus, potest et minus). Applied to the issue of setting the date of elections, this would mean that the President, who is explicitly empowered by the Constitution to set the dates of elections, could also annul that decision or fix new dates for elections.

^{26 This is a principle from Roman law, which often is not reflected in administrative law, where the power of an authority to annul its decision is strictly limited. In EU law, for instance, this is connected to the principle of legitimate expectations.}
