Section 28(5)(ii) in The Bengal Industrial Employment (Standing Orders) Rules, 1946
(ii)Where the enquiry is by an outside agency or, as the case may be where criminal proceedings against the workman are under investigation or trial, the subsistence allowance shall, for the first one hundred and eighty days from the date of suspension be equal to one-half of his basic wages, dearness allowance and other compensatory allowances to which workman would have been entitled to if he were on leave. If such enquiry or criminal proceedings gets prolonged and the workman continues to be under suspension for a period exceeding one hundred and eighty days, the subsistence allowance shall for such period be equal to three-fourths of such wages : Provided that were such enquiry or criminal proceedings is prolonged beyond a period of one hundred and eighty days for reasons directly attributable to the workman, the subsistence allowance shall, for the period exceeding one hundred and eighty days, be reduced to one-fourth of such wages.
