The move allows prosecutors in Poland to pursue investigations against the two lawmakers.
Dworczyk faces allegations related to using a private, unsecured email account for official duties, potentially exposing sensitive information, while Obajtek is accused of ordering surveillance of opposition politicians during his tenure as CEO of the state oil company Orlen.
Polish politicians welcomed the decision as a step toward accountability.
Michał Wawrykiewicz of the Civic Platform party said it opens the way for prosecutors to file charges, while fellow MEP Michał Szczerba highlighted that no one should hide behind parliamentary immunity.
Speaking in the European Parliament on Wednesday, Szczerba added that no "corrupt figures" from the Law and Justice (PiS) party would be shielded by European immunity and said the public would soon learn more about ongoing investigations by OLAF - the Euroepan Anti-Fraud Office - and the European Public Prosecutor's Office into cases such as the RARS and NCBR scandals.
Dworczyk and Obajtek described the decision as political revenge. Fellow PiS MEP Tobiasz Bocheński called it a double standard, noting that a similar immunity case involving an Italian communist MEP was not acted upon.
