The Rajya Sabha Secretariat said today the disqualification comes into effect from October 1, the date of his conviction.
Masood was sentenced to four years imprisonment by a Delhi court in connection with a medical admission scam. Masood is the first MP to have been disqualified after the Supreme Court struck down on July 10, 2013, sub section (4) of Section 8 of the Representation of the People Act as ultra vires the Constitution.
The amendment had protected convicted legislators against disqualification on the ground of pendency of appeal against their conviction in the higher courts.
The Rajya Sabha MP had been convicted on October 1 of cheating, forgery and corruption for nominating undeserving candidates to MBBS seats allocated to Tripura from the central pool during his 1990-91 tenure as MoS Health.
The court also found Masood guilty of conspiring with two others who have also been convicted.
CBI had alleged that some candidates got their names nominated for MBBS seats for academic session 1990-91 from accused Gurdial Singh, then Resident Commissioner Tripura and an IPS officer of Gujarat cadre who was on deputation to government of Tripura.
As per CBI, Singh and Masood had entered into a criminal conspiracy to nominate undeserving candidates from Tripura.
