There is no restriction in Cenvat Credit Rules, 2004 that legal services availed in respect of manufacture of excisable goods or provision of output service alone are input service and service tax paid on such input service alone is eligible as credit. Moreover as per rule 2 (l) of Cenvat Credit Rules. 2004-
“input service” means any service, -
(i) used by a provider of output service for providing an output service; or
(ii) used by a manufacturer, whether directly or indirectly, in or in relation to the manufacture of final products and clearance of final products upto the place of removal,
