After moving abroad I had legal questions.
I ended up on https://gram-news.com.ua/naslidky-neyavky-v-sud-st-268-kupap-shho-potribno-znaty-shhob-unyknuty-problem/.
It was hard to find clear info. Most sources were incomplete.
I read about Article 268 KUPAP and understood court rules.
On this site I found useful insights.
Good resource if you need info on Ukrainian law.
