"However, since there is a look-out notice against him from the Ministry of Corporate Affairs in Jet Airways
case, it (the decision) would have got in legal tangle. Therefore, he has joined GoAir in an advisory role," the source told PTI.
Dube boarded the Wadia group-promoted carrier last week, the source added.
A response is waited on the query sent by PTI on the development.
Lookout circulars were issued against former Jet Airways chairman and then promoter Naresh Goyal and Dube, among others, in late May for alleged financial irregularities at the airline.
The circular is issued against a person directing the immigration authorities to ensure that he or she does not leave India through an airport or seaport.
