Election commissioner Fuwad Thowfeek had called for the second round of voting to go ahead on Saturday in defiance of the court order, but was forced to back down when security forces were ordered to stop balloting.
"I have told police about the death threats I have been receiving since Saturday," Thowfeek told AFP by telephone. "These calls are from local numbers. The threats are directed against me as well as my staff and their families."
Nasheed won the first round of the presidential election on September 7 with 45.45 per cent. He sees the court decision as a conspiracy to prevent him taking power again, a year and a half after he was ousted following a police mutiny.
The Supreme Court suspended voting while it looks into complaints of electoral fraud in the first round by the third-placed candidate Gasim Ibrahim, one of the richest men in the nation of 350,000 Sunni Muslims.
