Libyans were meant to elect a president Friday hoping to help end years of turmoil, but the poll was delayed amid intense rivalries, UN failures and legal issues, experts say.
Analyst Jalel Harchaoui of the Global Initiative think tank pointed to "mistakes on the part of the UN and an attitude of extremely bad faith on the part of Libyan actors".
The ballot should have marked a fresh start for the oil-rich North African nation, AFP reported. But officials on Wednesday said holding the December 24 vote as scheduled was impossible, with the electoral commission suggesting a month's delay.
"Preparations for the election had been taking place in a highly volatile climate characterized by disputes over electoral laws and the eligibility of candidates," Amnesty International said in a report.
"Armed groups and militias repeatedly repressed dissenting voices, restricted civil society and attacked election officials," Amnesty's Diana Eltahawy said.
The delay is a major challenge to the United Nations-sponsored peace process.
"From the outset, holding elections in Libya was going to be a dangerous gamble," said Claudia Gazzini, from the International Crisis Group.
"But the immediate trigger for this halt in the electoral process was a controversy over the leading electoral candidates".
The electoral process began to come off the rails when Haftar-ally Aguila Saleh, speaker of the eastern-based House of Representatives, signed off on an electoral law in September without putting it to a vote.
Saleh "is responsible for the electoral laws, which are a real disaster", Global Initiative's Harchaoui said, adding that the problematic legislation was "absolutely crucial to explaining the failure of the elections".
Despite criticism, UN Libya envoy Jan Kubis offered support for the law.
After that, "the UN lost room to maneuver", Harchaoui said.
Wolfram Lacher, a Libya specialist at the German Institute for International and Security Affairs, criticized Kubis's "clueless backing" of Saleh's electoral law.
Analysts said that despite alarm bells, many in the international community clung onto the scheduled election date.
"Elections, however, are not the silver bullet that can deliver political stability," warned Hamish Kinnear, from risk analysis firm Verisk Maplecroft.
"As yet, there is no presidential candidate who stands much of a chance at taking power without being opposed by at least one well-armed faction."
For Lacher, the crisis was effectively inevitable ever since Saleh backed the electoral law.
"There were many scenarios how it could fail, and no shortage of insistent warnings," he said. "It was like watching a train wreck in slow motion."
