Justice Sunita Gupta reserved the judgement after the counsel for CBI and Masood concluded arguments in three different appeals filed by the convict.
Masood's counsel has sought suspension of his client's jail-term contending that the 68-year-old convict is acutely diabetic and is taking insulin several times a day besides other medicines for his ailments.
He has also submitted that the trial was going on against Masood for the past 17 years.
Masood is the first MP to lose his seat after the July 10, 2013 Supreme Court judgement which had removed the immunity for convicted lawmakers.
Masood's conviction and sentencing was the first case after the apex court judgement that struck down a provision in the Representation of the People Act, under which incumbent MPs and MLAs could avoid disqualification till pendency of the appeal against conviction in a higher court.
