As of making this market, el Presidente is reportedly in custody of the police. He has already been impeached by the Congress he attempted to dissolve, but will he face a prison sentence?

This market will resolve YES if Castillo is sentenced to any amount of jail time connected with charges stemming from his attempt to dissolve the congress and/or discard the current constitution and institute a new one (also any of his related actions, like attempting to institute a curfew or disarm Peruvian citizens). This is still YES even if it amounts to time served. If he is removed from office, fined, or otherwise punished while remaining free to walk the streets, this resolves NO.

If Castillo is still a free man by the close date (April 2024) this resolves no by default. I might bet on this if it seems worthwhile.
