He took oath as Judge of Telangana High Court on 26 March 2024.

As Calcutta Chief justice On 9 January 2026, Supreme court collegium led by CJI
Surya Kant recommended him to be appointed as chief justice of Calcutta High Court. Government cleared his appointment on 14 January 2026 and he took oath as chief justice on 16 January 2026. His tenure as chief justice of Calcutta High court coincided with
Special Intensive Revision of electoral rolls in
West Bengal. Due to alleged mistrust between
Election Commission of India and
Government of West Bengal, Supreme court has directed deployment of judicial officers to complete the process of SIR in the state; for this purpose role of Justice Paul as Chief justice of Calcutta became instrumental in completing the ongoing rolls revision. He cancelled the leaves of all judicial officers in the state as well as also requested services of judicial officers from neighbouring states such as
Odisha and
Jharkhand for this purpose. He also constituted appellate tribunal comprising former Calcutta HC chief justice
T. S. Sivagnanam for hearing appeals related to names deletion from electoral rolls. In March 2026, 7 judicial officers (including 2 women) engaged in SIR work were gheraoed at BDO office at
Malda, West Bengal and made hostages by angry mob, it was reported that during this incident Chief justice Paul repeatedly tried to contact West Bengal's
chief secretary but his calls went unanswered and situation was reportedly brought under control after midnight intervention of
Chief Justice of India Surya Kant. Supreme court rapped Bengal's chief secretary by reportedly asking him
to lower his security a little bit so that minions like Calcutta HC chief justice can speak to him. == References ==
