Mr. Shatadru Chakraborty, learned Advocate, who has represented the Respondent Authorities in this case has not seriously challenged the claim of the Writ Petitioner as to the admissibility of the amount of interest. Mr. Chakraborty has stated that initially the Writ Petitioner did not claim the interest amount and this Court considers that there not has been any scope for him to do the same as the Writ Petitioner would not have anticipated any delay in advance, in payment of his bills, as against the supplied goods. The further contention of Mr. Chakraborty is that the amount of consideration against his bill has been received by the Writ Petitioner without any objection raised as to alleged non-payment of interest. This submission of the respondents too, in the considered opinion of this Court, cannot be substantiated, in view of the subsequent two representations of the Writ Petitioner which are yet to be looked into by the Respondent Authorities.
