On Tuesday, the three-member tribunal, led by Justice Anwarul Haque, kept the verdict waiting to be delivered as both prosecution and defence had ended placing their arguments.
The trial began in May last year after an investigation in the case ended in September 2015.
Charges brought against the duo include killing of 62 people, abduction and detention of 11 people, and burning down some 250 houses in Nikli upazila during the war.
Of them, six charges, according to the prosecution, were proved beyond reasonable doubt.
