[13] Stefanchuk is a corresponding member of the National Academy of Legal Sciences of Ukraine [uk].

[18] On 7 October 2021, the Verkhovna Rada voted to dismiss Dmytro Razumkov from his post as Chairman of the parliament.

[2] On 15 October of the same year, Stefanchuk was appointed as member of the National Security and Defense Council of Ukraine by President Zelensky.

[20] On the morning of the Russian invasion of Ukraine on 24 February 2022, Stefanchuk was rushed to the Mariinskyi Palace, amid reports of assassination attempts on Volodymyr Zelenskyy, as his role meant he would have to take command of the country had the president been killed.

However, Stefanchuk has rejected Putin's claims, citing the legal inability to hold elections under martial law and the Ukrainian Constitution setting the presidential mandate to last until the election of a successor at the end of martial law.
