41. Burden of proof, etc.-In the case of any complaint under clause (a) of section 36, -(a) Whenever it is shown that a railway administration charges one trader or class of traders or the traders in any local area, lower rates for the same or similar goods or lower charges for the same or similar services than it charges to other traders in any other local area, the burden of providing that such lower rate or charge does not amount to an undue preference, shall lie on the railway administration;
(b) In deciding whether a lower rate or charge does not amount to an undue preference, the Tribunal may, in addition to any other considerations affecting the case, take into consideration whether such lower rate or charge is necessary in the interests of the public.
