Due to lack of knowledge & oversight, Project Engineer of Supplier Company "Y" & Company "X" ( who has given the project award) does not avail cenvat credit on Free Supply Materials for Project capital & revenue nature items ( free means no payment for materials value but all duties) and "Y" now requests "X" to pay back excise duty ( which was paid by "Y" at the time of despatch of value , after 5 years and then claim cenvat credit, is it legally sustainable.Kindly advise with case laws, rules, if any.
Thanks in advance.
