In all cases, there is a clear mention in the Constitution about the obligation to introduce the Bengali language in all spheres of life.
There are also directives of the High Court to introduce Bangla and prevent its use in distorted forms.
But these provisions and instructions are not being obeyed on various excuses.
English is still the language used in most cases in the Supreme Court and Judicial Courts.
Apart from this, Bangla is still neglected in government and non-governmental institutions and in other fields as well.
However, the use of Bengali in the courts is gradually increasing.
At a function at the Bangla Academy on February 15, 1971, Bangabandhu Sheikh Mujibur Rahman said, "I am announcing that the Bengali language will be introduced in all parts of the country from the day we come to power."
On December 30 in 1971, Prime Minister Tajuddin Ahmed formed a new cabinet and declared, 'Bengali will be the official language of the country.'
Then Article 3 of the Constitution said, 'Bangla is the state language of the republic.' In order to implement this provision properly, the Bengali Language Introduction Act was enacted on March 8, 1987.
Section 3 (1) of the Act states, 'After the introduction of this Act, documents and correspondence, Q&A (question and answer)and other legal functions must be carried out in all areas of Bangladesh except in government offices-courts, semi-government and autonomous bodies except in contacts with foreigners.
“You have to write in Bengali,” the section said, adding that "If any person applies or appeals in any language other than Bengali in the said workplace, it will be deemed illegal and invalid."
In the case of education, research, billboards, signboards and official letters in various government offices, English is still widely used.
Apart from this, orders have been issued at different times for the application and use of Bengali language at all levels, but in many cases the respective offices or courts do not comply with it.
The rules of the Supreme Court also mentioned that Bengali language can be used along with English language.
But according to the Supreme Court rules, English is being used in most cases. As a result, the use of Bengali language is shrinking day by day and the level of distortion of the language is increasing.
Although a number of judges have given and are giving orders and verdicts in Bengali, however, Bengali has not yet been fully introduced in the higher court.
Former Chief Justice ABM Khairul Haque has set a unique example in this regard. He played a strong role in the introduction of Bengali language in the higher court by writing the judgment of the much-discussed Fifteenth Amendment to the Constitution in Bengali.
On February 16, 2012 and February 17, 2014, the High Court issued directions on the introduction of Bengali language at all levels and the prevention of distorted pronunciation of Bengali language on radio and television so that a rule was issued not to broadcast programmes on radio and television with distorted pronunciation, language satire and pollution.
But the rule has not been settled even today.
