The JVP said that previous government appointed commissions were a waste of public money, as he criticised former Sri Lankan President Mahinda Rajapaksa for paving the way for a hybrid court to prosecute war crimes.
JVP Propaganda Secretary Vijitha Herath said appointing the Lessons Learnt and Reconciliation Commission and Maxwell Paranagama Commission had allowed the United Nations Human Rights Council to become involved in the island's reconciliation process, according to The Island.
Despite this, Mr Herath stated that his party were "still demanding a domestic investigation and condemn any international interference in the country".
There were no legal provisions for foreign judges or lawyers to work in Sri Lankan courts he added, stating that existing laws would not allow that to happen.
