The Age of the Convicted Ex-President: Seoul Joins a Global Reckoning

Rio Times · Analysis

*From Seoul to São Paulo, the world’s courts delivered the same blunt verdict this week. No president is above the law any more, except in a few stubborn corners of the map, where they still are.*

A Verdict in Seoul, A Pattern That Keeps Repeating

This week’s ruling in Seoul is not really a Korean story. It just happens to be the one making headlines out of Asia today.

Strip away the country and the constitution, and it becomes something readers in São Paulo, Bogotá and Lima will recognise instantly. A former head of state, once untouchable, is now formally a criminal.

South Korea’s Supreme Court upheld a seven-year prison sentence for Yoon Suk Yeol this week. The ruling closed the first of several criminal cases stemming from his brief attempt to impose martial law.

The court acted on Thursday in the first case to reach the country’s highest court from Yoon’s several criminal trials. Those trials relate to his brief imposition of martial law in 2024.

It is a tidy, procedural sentence. It is also part of a much bigger global story that runs straight through Latin America, the region that pioneered the modern art of prosecuting ex-leaders.

This is the region still writing the rulebook on presidential accountability. Seoul’s verdict simply confirms the practice is spreading, which makes this the must-read pattern of the day.

The question worth asking is not why Yoon was convicted. It is why so many of his counterparts, across the Pacific and the Atlantic, are ending their careers in the dock rather than in quiet retirement.

Korea’s Long Wait for Closure

Yoon’s fall was swift and dramatic, even by the standards of a country used to political drama. He declared martial law in December 2024, deployed troops to the National Assembly, and was gone from office within weeks.

The court’s reasoning this week went well beyond the original declaration itself. It upheld an April ruling by the Seoul High Court, which found Yoon guilty on several counts.

The court found he infringed on Cabinet members’ right to deliberate before declaring martial law. It also found he falsified the official proclamation to cover up the lapse, then later destroyed the document.

The Seoul High Court further found that Yoon deployed presidential security forces to illegally resist law enforcement. Those officers sought to arrest him weeks after his impeachment.

Commuters gathered around screens at Seoul’s railway station to watch the ruling broadcast live. It was a small but telling ritual of a nation needing this chapter closed.

What makes the Korean case notable is the speed and totality of the institutional response. Martial law lasted only hours before lawmakers broke through a blockade of heavily armed soldiers and police at the National Assembly to vote it down.

Korea shows a democracy’s institutions working exactly as designed under pressure. It is a template Latin America knows painfully well from its own recent history.

Peru: The Prison Built for Presidents

Nowhere has this pattern gone further than Peru. There, accountability for ex-leaders is no longer an event but a fixture of the political landscape.

The numbers alone tell the story. Four former presidents are currently serving time in Lima’s Barbadillo prison, a single facility that has become a living monument to unaccountable power finally answering for itself.

That prison’s population keeps growing. It holds Toledo and former President Pedro Castillo, who faces what could be a 34-year sentence for his 2022 attempt to dissolve Congress.

The same prison also housed the late Alberto Fujimori. The former Peruvian president was imprisoned there until his release in 2023.

Alejandro Toledo’s case shows how far back the reckoning reaches. In October 2024, he was sentenced to 20 years and six months for accepting $35 million in bribes from the construction firm Odebrecht.

Toledo is a 78-year-old economist who holds a doctorate from Stanford University. He governed the nation between 2001 and 2006.

This is structural, not incidental. Since the turn of the millennium, at least seven presidents have faced trial or legal challenges over corruption or human rights abuses, while an eighth shot himself dead as police were closing in.

Francisco Sagasti and Valentín Paniagua are the exceptions.

Brazil’s Reckoning: Twenty-Seven Years for a Coup

If Peru shows what happens when accountability becomes routine, Brazil shows what happens when it finally arrives. Here it came after decades of institutional caution.

The scale of the sentence stunned even hardened court-watchers. The latest to join this list is Jair Bolsonaro, who was sentenced to 27 years in prison by Brazil’s court.
