The HC bench of Justice FRM Nazmul Ahasan and Justice KM Kamrul Kader passed the order.
It also issued a rule asking the authorities concerned to explain as to why the ineffectiveness of the respondents in displaying and preserving the portrait of Bangabandhu at the courtrooms across the country would not be declared illegal.
Supreme Court lawyer Subir Nandi Das filed a writ petition to the court seeking its order to hang the portrait of Bangabandhu at all the courtrooms on August 21.
He said in many countries, including India, portrait of their Father of the Nation are displayed at office and courtrooms and it is obligatory by the constitution.
Secretaries to the Law Ministry, Public Works Ministry, Finance Ministry and registrar general of the Supreme Court and registrars of High Court division were made respondents to the rule.
