With today's swearing-in, the total number of judges in the apex court has gone up to 25.
Earlier, the ceremony was surrounded by a controversy over the order in which the three judges were sworn-in.
"The government has given the message that if a judge doesn't make a judgement in their favour, he may be treated the same. I believe that this day will be seen as a 'black day' in the history of Indian judiciary. This is the arrogance of the government," Sibal told ANI.
As per convention, the seniority of Supreme Court judges is determined on the basis of their swearing-in as judges of High Courts.
Last month, the Supreme Court collegium had unanimously reiterated the recommendation for elevation of Justice K.M. Joseph to the apex court.
The decision was made after the Centre rejected the collegium's recommendation for the elevation of Justice KM Joseph to the Supreme Court earlier this year.
The government drew flak when Justice Joseph's name was recommended by the collegium in January.
