This article examines OAB's struggle, through its highest directive instance, the Federal Council, against Goulart's Government. OAB oppositionist operation should be understood into the civil mobilization scenario which provoked a campaign of destabilization of the Federal Government. After Goulart's deposition, OAB, as an institution, and the federal counselors, individually, cooperated on an active basis with the military dictatorship over its early years. It is proposed that OAB's oppositionism against Goulart's Government arose out of four factors: federal counselors' social and economic interests; their politic and partisan bonds; the dominant politic culture in the Federal Council; corporate and institutional issues.
