This conclusion is supported by the general interpretative rule, according to which express regulation of emergency powers in the Constitution and laws restricts recourse to any complementary unwritten emergency powers to very exceptional situations; primarily to situations of factual or legal impossibility which are not explicitly provided for by written emergency law. Cancelling elections is possible only in situations which meet the requirement for declaring a state of emergency. However, the applicable constitutional rules for emergency situations were not followed in this case. Neither was there a political consensus, which would have allowed for the establishment of an ad hoc legal basis.
