In November last year, the Delhi High Court had upheld its verdict in the case following which the convicted persons appealed in the Supreme Court.
The CBI told a bench of Justices S A Bobde and S A Nazeer that Kumar, who was a sitting MP in 1984, was the kingpin of the massacre of Sikhs in the national capital in 1984.
The violence had claimed 2,733 lives in Delhi alone.
Justice Khanna had earlier also recused himself from hearing Kumar's appeal.
The CBI said that Kumar's 'political clout clouded fair and speedy investigation and derailed justice for the victims' of the 1984 anti-Sikh riots.
