The current tax chief S Angammana, had been moved to the finance ministry, the newspaper said. "I will serve in both positions," The Sunday Times newspaper quoted Justice Chitrasiri as saying.
"Under Article 110 of the Constitution, the President can assign other work to judges of the Supreme Court and the Court of Appeal.
"I believe the appointment is being made under this provision. The Tax Department position is lower than my current position.
"I will continue in the Court of Appeal and at least spend one day a week there."
Justice Chitrasiri had also served in the Commercial High Courts of Colombo and had been a former registrar of companies.
