The High Court (HC) has ordered use of "Joy Bangla" as national slogan in all kind of state programmes from December 16 onwards.
A bench of Justice F R M Nazmul Ahsan and Justice K M Kamrul Quader passed the order today.
The verdict on the matter will be delivered on January 14.
A writ petition was filed on December 4, 2017 by Supreme Court lawyer Bashir Ahmed saying "Joy Bangla" was the slogan of freedom fighters as well as all people of Bangladesh during the Liberation War in 1971.
It will be a symbol of national spirit and patriotism among the future generation if it becomes the national slogan, he said.
Upon the writ a rule was issued by the bench of Justice Quazi Reza-Ul Hoque and Justice Mohammad Ullah asking the government that why the slogan would not be declared as the national one.
"The slogan brought the people together to fight in the liberation war under the leadership of Bangabandhu Sheikh Mujibur Rahman," the court said.
"We gained freedom from Pakistan for this," HC added.
The respondents to the rule were secretaries to the cabinet division, Law Ministry and Education Ministry.
