RIO DE JANEIRO, Dec 20 () - Brazilian investors' association Abradin has filed a motion with a São Paulo court questioning the legality of a tie-up between U.S. planemaker Boeing Co and Embraer SA.
The motion asks the court to determine whether Embraer shareholders should be eligible for a public tender offer. Abradin could bring legal action against the deal if a public tender is not launched.
"We understand that this is an illegal operation," Abradin's president, Aurelio Valporto, told .
Embraer and Boeing finalized a deal this week in which Embraer will sell 80 percent of its commercial jet unit, netting $3 billion in proceeds.
Both companies did not immediately comment on the matter.
