S. 260A : Appeal-High Court-Delay of three years -Not explained sufficient cause in delay in filing an appeal-The lack of sincerity, or rather complete absence thereof on the part of the Revenue in this case was glaringly conspicuous by its having not even filed an application seeking condonation of this colossal delay of about three years in filing these appeals-Delay is not condoned.[S.260A(1) 260A(2)
