In 2010, Pioneer launched a second action for failure to act (case T-164/10) against the Commission for not having, following the absence of opinion by the Regulatory Committee, referred to the Council a proposal for an authorisation decision , in line with the comitology procedure applicable at the time.
2010. aastal algatas Pioneer teise tegevusetuse hagi (kohtuasi T-164/10) komisjoni vastu, sest pärast seda, kui regulatiivkomitee jättis arvamuse esitamata, ei saatnud komisjon loa andmise otsuse ettepanekut vastavalt sel ajal kehtinud komiteemenetlusele edasi nõukogule.
