"

In 2015, the term of five judges was set to expire, three of which between Sejm election day and the new legislature's session, and two the month after. PO tried to appoint them in advance (they were: Roman Hauser, Krzysztof Ślebzak, Andrzej Jakubecki, Bronisław Sitek and Andrzej Sokala) but their oath was denied by the new PiS President, Andrzej Duda. As a result, they never sat. The new PiS majority nominated three other judges on 2 December 2015 (Henryk Cioch, Lech Morawski, Mariusz Muszyński) and two others the next week (Piotr Pszczółkowski, Julia Przyłębska), who were immediately sworn in. Cioch and Morawski later died while in office, and were replaced by Justyn Piskorski and Jarosław Wyrembak.[citation needed]
