BOGOTÁ, Colombia — Colombia’s Supreme Court ordered on Tuesday the detention of a former president and longtime giant of Colombian politics, Álvaro Uribe, amid an investigation into whether he committed acts of fraud, bribery and witness tampering.
The decision is a landmark in a nation accustomed to back door deals between politicians who were rarely called to answer for their actions in court.
While some other nations in Latin America have tackled corruption aggressively in recent years, sometimes prosecuting presidents, Colombia has infrequently indicted major political players.
Widely viewed as the most powerful Colombian politician of the last two decades, Mr. Uribe had been the subject of investigation for years, but this is the closest he has come to facing a panel of judges. His ability to avoid prosecution had led many Colombians to call him the “Teflon president.”
The court order has the potential to upend the political landscape in Colombia. And it makes him the first president in modern Colombian history to face detention.
He will spend the time under house arrest, the court said. While this is far less severe than time in prison, Mr. Uribe said he was dreading the confinement.
“Being deprived of my freedom causes me deep sadness,” Mr. Uribe wrote on Twitter on Tuesday, “for my wife, for my family and for the Colombians who still believe that I have done something good for the country.”
Mr. Uribe was president from 2002 to 2010, and continues to wield outsize power from his seat as senator. The current president, Iván Duque, was little known before Mr. Uribe backed him — and he won election in 2018 with a promise to restore Mr. Uribe’s legacy.
Mr. Uribe’s standing in Colombia makes his detention “really something significant for our country,” signaling a possible shift toward forcing previously untouchable politicians to answer for alleged crimes, said Francisco Bernate, a law professor at the Universidad del Rosario in Bogotá, the capital.
His detention threatens to further polarize Colombian politics, heightening conflict between Mr. Uribe’s allies and his opponents over the former president’s legacy.
On Tuesday, Mr. Duque attacked his own judicial system for pursuing his mentor, denouncing the fact that Mr. Uribe would not be allowed to remain free pending the resolution of his case — something that criminals and guerrillas have been allowed to do, he noted.
“It hurts, as a Colombian,” Mr. Duque said, that “an exemplary public servant, who has occupied the highest post in the state, is not allowed to defend himself in liberty, with the presumption of innocence.”
Prosecuting judges have not yet brought formal charges against Mr. Uribe, but the Colombian justice system allows judges to detain him pending an indictment if they believe he is a flight risk or could tamper with evidence. He could be held for up to a year as the investigation moves along.
The case stems from an investigation that the Supreme Court started in 2018. The court’s judges are examining whether Mr. Uribe tried to influence the testimony of an alleged paramilitary member, Juan Guillermo Monsalve, pushing Mr. Monsalve to retract statements in which he linked Mr. Uribe to the creation of paramilitary groups.
Mr. Uribe has denied a connection to paramilitary groups, instead saying he fought against them. He has also denied asking anyone to obstruct justice.
If found guilty, Mr. Uribe could face approximately six to eight years in prison, Mr. Bernate said, though it is likely he would spend the time under house arrest instead.
On Tuesday, as darkness fell, Colombians throughout the capital, Bogotá, leaned out their windows to shout and bang pots in celebration of Mr. Uribe’s detention.
But in Medellín, an Uribe stronghold, hundreds of supporters gathered to show their support. “He gave us security like no other president did,” said Catalina Pozada, 42, who credited the former president for forcing one of the country’s guerrilla groups to halt kidnappings and highway blockades.
The court’s decision could also affect the current president, Mr. Duque, whose popularity sagged during his first year in office, until he got a bump for his handling of the pandemic. His supporters on the right may turn against him for not doing more to keep his mentor free, while critics on the left may use Mr. Uribe’s detention to taint Mr. Duque and associating him with criminals.
Mr. Duque defended his mentor on Tuesday, saying the former president embodied “honorability.” Speaking on a national radio station, Mr. Duque said the idea that Mr. Uribe would be aligned with paramilitary groups was “absurd.”
The case is one of several investigations in the Supreme Court into Mr. Uribe’s conduct over the years.
The investigation came about after Mr. Uribe accused a political opponent, Senator Iván Cepeda, of manipulating witnesses against him, prompting an investigation into Mr. Cepeda. That inquiry was closed in 2018, and the court decided instead to proceed with the investigation into Mr. Uribe for allegedly bribing a witness and procedural fraud.
“This is an important shift toward strengthening democracy,” Mr. Cepeda said. “Colombia has been a country with monarchic tendencies in which certain political figures are untouchable. Well, here there cannot be anyone above the constitution, above the law and above justice.”
