The warning signs for Guatemala’s fragile democracy started flashing as soon as Mr. Arévalo, who is the son of Juan José Arévalo, a former president still exalted for creating Guatemala’s social security system and protecting free speech, squeaked into a runoff over the summer.
A prosecutor quickly moved to suspend Mr. Arévalo’s insurgent party, Movimiento Semilla (the Seed Movement), and when he resoundingly won the election in August, the judicial authorities and members of Congress expanded their campaign against the president-elect and his allies.
These efforts reached a fever pitch in recent days as prosecutors and Congress took steps to strip Mr. Arévalo of his immunity from prosecution and effectively nullify the election results. Together with other efforts to lift Mr. Arévalo’s immunity and lock up some of his allies, these moves could open the way for judicial officials to seek his arrest and disrupt the scheduled transfer of power in mid-January.
Leonor Morales, a prosecutor who spearheaded the latest efforts against Mr. Arévalo, accused Semilla of using fraudulent signatures to register as a political party. “Semilla was never born through legal means as its constitution was through corrupt and illegal actions,” Ms. Morales told reporters last week.
In seeking to invalidate Mr. Arévalo’s party, and potentially by extension the election outcome, an alliance of conservative prosecutors and members of Congress, working without pushback from the departing president, Alejandro Giammattei, is pressing ahead with a multiyear drive to consolidate and protect their power, legal experts said.
Alejandro Balsells, a constitutional law authority, said the officials ramping up the legal attacks on the president-elect were in “burn-the-ships mode,” comparing their tactics to those of the Spanish conquistador Hernán Cortés, who scuttled his ships to prevent his men from turning back on what became the conquest of the Aztec Empire.
In this case, Mr. Balsells said, prosecutors and legislators were engaged in a scheme to overturn the election results and were using nearly every tool at their disposal to get the courts and Congress to move against Mr. Arévalo.
For some of Mr. Arévalo’s supporters, such positioning is tantamount to stealing the election. “It will be a miracle if Arévalo takes office,” said Claudia González, a prominent human rights lawyer who was imprisoned this year for 82 days.
Ms. González had worked for a United Nations-backed anticorruption mission that was shut down, transforming Guatemala from a staging ground for rooting out graft to a country where dozens of judges and prosecutors battling corruption have been forced into exile.
This shift has proved vexing for the Biden administration, which has repeatedly expressed support for Mr. Arévalo and has been trying to bolster anticorruption efforts in Guatemala. The U.S. Treasury Department this month imposed sanctions on Miguel Martínez, a close ally of Mr. Giammattei, over widespread bribery schemes.
But the drive by Guatemalan officials to keep Mr. Arévalo out of office makes clear the current limits of American influence in Guatemala, where the United States once held considerable sway.
Mr. Arévalo’s supporters, pushing back, are in a tense standoff with the authorities in parts of Guatemala’s capital. After taking to the streets in October for nationwide antigovernment demonstrations, Indigenous protesters remain camped in front of the attorney general’s headquarters to show support for the president-elect.
“Our fight today is for the little bit of democracy we have left,” said Rigoberto Juárez, 66, an Indigenous leader from Huehuetenango, in Guatemala’s western highlands. “We deposited our confidence in Arévalo,” he said. “Nullifying our votes amounts to an attack on Indigenous peoples.”
Fears are building over the lengths that Mr. Arévalo’s adversaries might go to in order to prevent him from taking office. The latest magistrates to flee the country were members of the authority overseeing the country’s elections, which had certified the voting results and blocked the suspension of Mr. Arévalo’s party. They boarded flights out of Guatemala the same day Congress stripped them of their immunity from prosecution.
Mr. Arévalo said that members of the ruling alliance had told him that bribes were paid to secure the votes of legislators in favor of a “package deal” that included the budget and removing the election magistrates’ immunity. “We have been told of sums that have been progressively increasing,” Mr. Arévalo said. “They started by offering 150,000 quetzals for the budget approval. Later, they told us they raised the amount to 200,000, then to 250,000, and later added more.” (250,000 quetzals is about $32,000); these claims could not be independently verified.
Others are not so sure that Mr. Arévalo’s foes will ease up their attacks. Will Freeman, a fellow in Latin America studies at the Council on Foreign Relations, said the Guatemalan authorities had weaponized the law time and again to crack down on anticorruption initiatives.
“If it was just to tie Arévalo’s hands, they’ve already done that,” Mr. Freeman said. “We’re seeing a drive to stop Arévalo from taking office.”
For those caught in the cross hairs as Guatemala’s prosecutors move against Mr. Arévalo and his allies, that means the wait until the president-elect’s scheduled inauguration is infused with anxiety. “There’s this fear that remains, a sort of trauma, that stays with you,” said Marcela Blanco, 23, a member of Mr. Arévalo’s party who was arrested in November and held for 11 days. “You feel unsafe in your own home — like at any moment,…”
