Date: 2026

## The fact

On 11 March 2026 [José Antonio Kast](/people/jose-antonio-kast) was sworn as president of Chile, succeeding [Gabriel Boric](/people/gabriel-boric) at the constitutional date. Kast had won the 14 December 2025 runoff with about 58 percent against [Jeannette Jara](/people/jeannette-jara).

## Context

Immediate re-election is barred. Jara had been labour minister. Kast and Jara are unresolved person candidates. This run does not mint them.

14 December 2025 runoff; 11 March oath. Store the handover date as Boric’s last presidential day. Keep Boric leaves office as José Antonio Kast is sworn after the 2025 runoff on 2026-03-11 separate from neighbouring 4 September 2022 Rechazo, Ley 21.560, 17 December 2023 En contra, Ley 21.735, and the 11 March 2026 handover.

The president of Chile is head of state and head of government. He can promulgate statutes Congress sends and order border patrols. He does not sit as a SERVEL teller, a Constitutional Convention drafter, a Carabinero at a checkpoint, or a Peruvian border clerk.

## Significance

The path is capacity for peaceful transfer: a completed constitutional rotation after a decisive runoff.

## What is established and what is not

Established: Boric left office on 11 March 2026; Kast was sworn; Jara had lost the runoff.

Not established: That the handover rebates Rechazo, or a unique later homicide coefficient from the oath hour.

What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Boric completed the term. Kast is unresolved.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Boric leaves office as José Antonio Kast is sworn after the 2025 runoff, not a later speech about Boric leaves office as José Antonio Kast is sworn after the 2025 runoff.

Co-authors and later implementers named in Context remain on the file. Boric leaves office as José Antonio Kast is sworn after the 2025 runoff on 2026-03-11 is not a licence to treat every later Government of Chile communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average Boric leaves office as José Antonio Kast is sworn after the 2025 runoff into a personality. The contribution described on this Person row is limited to Congress received the oath. Boric completed the term. Kast is unresolved. That limit is the alternative to treating office-holding as authorship of every later series.
