After hearing the case, Justice Rezwan Chowdhury said the decision will be given after the investigation.
A case was filed with a Shatkhira court against opposition Chief Whip Mashiur Rahman Ranga on Thursday for making derogatory remarks on slain pro-democracy activist Noor Hossain.
Satkhira District Lawyer Association President Shah Alam filed the case.
After hearing the case, Judge Rezwan Chowdhury said the decision will be given after the investigation.
On November 13, Ranga extended unconditional apology for his remark on Noor Hossain.
He offered the apology as he stood in the House to make his personal statement under section 274 of the rules of procedure.
On November 12, Ranga faced fierce criticisms even by two senior MPs of his own party alongside others in the Jatiya Sangsad for his recent offensive remarks against slain pro-democracy activist Shaheed Noor Hossain.
They demanded Ranga apologise before the nation standing in Parliament for his insulting remarks against Noor Hossain, a young pro-democracy activist, sacrificed his life to end the autocratic regime of HM Ershad on November 10, 1987.
Earlier, Ranga at a discussion said, "Who was Noor Hossain? An addict... a Yaba abuser, a Phensedyl abuser! Two democratic parties -- Awami League and BNP -- are overenthusiastic about him. This day is observed as Noor Hossain Day."
