Government supporters took to the streets calling for Ms Bandaranayake's (pictured) resignation, while Buddhist monks, Catholic priests, opposition MPs, judges, lawyers and trade unionists rallied in support of her.
The government has accused Ms Bandaranayake of misusing power and having unexplained wealth. She denies any wrongdoing.
Opposition parties insist that the impeachment attempt is unjustified and is aimed at stifling judiciary independence and concentrating power with President Mahinda Rajapaksa.
Sri Lanka's influential Buddhist monks, lawyers, trade unions and rights activists have called on the government to withdraw the motion, saying it threatens the judiciary's independence.
"We urge the government to withdraw this motion even at this stage," said lawyers' spokesman JC Weliamuna.
He said the "government is hell-bent on getting rid of the chief justice" for ruling against it several times.
