There was a decision of the Ukrainian constitutional court that the powers of the president cannot exceed five years. After five years, the president either calls elections or surrenders his powers to the speaker of the Rada, I don't remember to whom. The Cabinet resigns, and the Rada appoints another Cabinet. And so on.
Then the deal was for deposed President Yanukovych. So he couldn't come back.
And now it hit Zelensky.
So no matter how you look at it, Zelensky is not the president from today.
There is a ban on parliamentary elections written in the Constitution. Exactly parliamentary.
There are no prohibitions on holding presidential or any other elections.
Because according to the Constitution, Ukraine is a parliamentary-presidential republic, the parliament and its decisions must be above the decrees of the president.
But this is all in theory. Whoever grandpa Biden petted is legitimate.
I looked it up:
Article 64
Constitutional human and citizen’s rights and freedoms shall not be restricted,
except in cases envisaged by the Constitution of Ukraine.
Under conditions of martial law or a state of emergency, specific restrictions on
rights and freedoms may be established with the indication of the period of effect
of these restrictions. The rights and freedoms envisaged in Articles 24, 25, 2 7, 28,
29, 40, 47, 51, 52, 55, 56, 57, 58, 59, 60, 61, 62 and 63 of this Constitution shall
not be restricted.
However, Article 70, which is about the right to vote, is not excluded:
Article 70
Citizens of Ukraine who have attained the age of eighteen on the day elections and
referendums are held, have the right to vote at the elections and referendums.
Citizens deemed by a court to be legally incompetent do not have the right to vote.
This means Ukraine can hold elections during wartimes or not, both is constitutional.
But according to the constitution, the President will never again be a regular citizen:
Article 105
The President of Ukraine enjoys the right of immunity during the term of authority.
Persons guilty of offending the honour and dignity of the President of Ukraine are
brought to responsibility on the basis of the law.
The title of President of Ukraine is protected by law and is reserved for the
President for life, unless the President of Ukraine has been removed from office by
the procedure of impeachment.
This means Zelensky will be President forever.
