 On the other hand, if the Tribunal feels that the bill does have the circumventing or curtailing effect, and the President either has withheld or withholds his assent to the bill, the Prime Minister may direct that the bill be submitted to the electors for a national referendum.In that case, the bill only becomes law if it is supported by not less than two-thirds of the total number of votes cast at the referendum.If 30 days have expired after a bill has been presented to the President for assent and he or she has neither signified the withholding of assent nor referred the Bill to a Constitutional Tribunal, the bill is deemed to have been assented to on the day following the expiry of the 30-day period.
