When the case was taken up today, the Bar Association of Sri Lanka (BASL) counsel argued that the body has a legal right to submit this petition and that the move was aimed at preserving the independence of the judiciary.
The impeachment against 54-year-old Bandaranayake was moved by the government based on 14 charges of personal and financial misconduct.
The arguments went over an hour and it was decided that the petition will be taken up for hearing on January 21, 2013.
The BASL case states that the 11-member parliamentary select committee appointed to probe Bandaranayake must wait for the Supreme Court's interpretation of the constitutionality of parliament's standing order 78A which governs the impeachment procedure.
The BASL argues that standing order 78A is an infringement of fundamental right to equality and equal protection before the law.
The Supreme Court and the legislature are currently embroiled in a tussle over the chief justice's impeachment.
In response to a Supreme Court notice that members of the PSC must appear before it, the parliamentary speaker snubbed the order.
Bandaranayake, the first woman head of the Supreme Court, is set to appear before the PSC tomorrow in the continuation of the probe against her.
She faces sacking through the parliamentary select committee process which is examining 14 charges of improper conduct against her.
