Because that's totally out of the jurisdiction of the International Court of Justice.
And what about Constitutional Court of Ukraine?He could applied there and prove that he still is legitimate if he is so right.
If Yanu thought that he couldn't remain President, he would have resigned. But he didn't.
Yes, instead of made it as it should've been done, he just leave all, leave his duties which assigned to him by the Constitution, and runaway.
That's stupid. Sometimes running away can be the duty of a president. The Polish government ran away too when the country was invaded by Nazi Germany.
It can't be compared, different things
Anyway, there was nothing in the constitution which said that the Parliament could remove the President if, according to their own foolish opinion, the President wasnt "performing his duties" anymore. Article 111 of the constitution allowed to impeach the president in case of "state treason or other crime." Running away is certainly not a state treason. However, ploting to overthrow the legitimate president is a state treason.
And again - Parliament does not remove Yanu, they just made resolution which confirmed, that President self-removed and cannot perform his duties, and made further decision because of it.
To make it more clear.
1. Yanu runaways and withdrewed from his duties of President of Ukraine by himself in the way that is not specified in the Constitution(in other hand, there also not specified that if he runaways, he still remains President)- take is as fact1.
2. Parliament gather together and check - President is somewhere no one knows for sure where, does not do what he should do - fact1 confirmed, so they made an appropriate decision in a Resolution
3. fact1 about Yanu self-removing wasn't appealed by him or anyone other in Constitutional Court of Ukraine or any other, and wasn't officially declared as one that does not held, he also didn't tries to return to perform of his duties.
4. So if it is held, then Resolution with decision to ensure him self-removed do not have anything against the law.
Indeed he is politically dead(maybe real as well), PP is recognized even by Russia, i see no point to bother on this topic again and again.
