Concerning the deprivation of the right to vote and to be elected, the Code of Good Practice in Electoral Matters states:

“i. provision may be made for depriving individuals of their right to vote and to be elected, but only subject to the following cumulative conditions:
ii. it must be provided for by law;
iii. the proportionality principle must be observed; conditions for depriving individuals of the right to stand for election may be less strict than for disenfranchising them;
iv. The deprivation must be based on mental incapacity or a criminal conviction for a serious offence; v. Furthermore, the withdrawal of political rights or finding of mental incapacity may only be imposed by express decision of a court of law.”
