Haji Anayat Ali, the chairman of the Legislative Council, administered the oath, an official spokesman said.
Tassaduq Mufti was nominated as an MLC by Governor N N Vohra on December 22, 2017.
In the second expansion of the Cabinet in the state last year, Tassaduq Mufti - the younger brother of Chief Minister Mehbooba Mufti - and another PDP legislator Javaid Mustafa Mir were administered the oath as ministers of state on December 28. Tassaduq Mufti was later given the tourism portfolio.
Tassaduq Mufti, 45, a famed cinematographer, formally joined the PDP at an event organised to commemorate his father Mufti Mohammed Sayeed's first death anniversary on January 7 last year.
On December 22, he was nominated by the governor as a member of the legislative council to fill a vacancy created by the resignation of Vikramaditya Singh from the PDP on October 22.
