Potential weakening of Lula's executive authority and rule of law regarding accountability for 2016 coup attempt and January 8 riots.

Indirect impact through potential political instability and reduced investor confidence in Brazil's institutional framework, which could affect currency stability, inflation, and interest rates for households.

The STF's intervention signals potential constitutional crisis between branches of government. Outcome could establish precedent for veto override authority, affect sentencing guidelines for political crimes, and influence future legislative-executive relations in Brazil.
