condemned Peiris' appointment, describing it as a "further assault on the independence of the judiciary".
Maithripala Sirisena, the president elected on 8 January 2015, refused to take oaths before him on the basis his appointment was illegal and took oaths before Justice Hon. K. Sripavan, the most senior judge of the Supreme Court.
According to Sirisena, Mohan Peiris visited him several times begging not to remove him and promising to deliver judgements according to his wishes.
On 28 January 2015, the Government of Sri Lanka acknowledged that the appointment of Mohan Peiris as the chief justice was void at its inception as Dr. Shirani Bandaranayake was not impeached lawfully and therefore, no vacancy existed for the post of chief justice. That paved the way for Dr. Shirani Bandaranayake to resume duties as the chief justice of Sri Lanka.
