The Court of Arbitration for Sport (CAS) has rejected Prince Ali Bin Al Hussein's attempt to have Friday's FIFA presidential election postponed.
Prince Ali's lawyers had made the application after his request for transparent voting booths to be used were rejected by the election commission at world football's governing body.
But on Wednesday afternoon CAS released a statement confirming it would not intervene to halt the election.
The statement read: "The request for provisional measures has been rejected by the President of the CAS Appeals Arbitration Division. The full order with grounds will be communicated in a few days.
"On 22 February 2016, HRH Prince Ali Al Hussein filed an appeal against a decision taken by the FIFA Ad-hoc Electoral Committee dated 15 February 2016 in which it declined to incorporate the use of transparent voting booths for the upcoming FIFA Presidential Election.
"In an urgent request for provisional measures, HRH Prince Ali Al Hussein sought an order that FIFA be directed to use transparent voting booths, as well as independent scrutineers, in order to safeguard the integrity of the voting process and to ensure that the vote is conducted in secret.

"In addition, HRH Prince Ali Al Hussein also asked for the FIFA Presidential Election to be postponed in the event the CAS could not rule on the request for provisional measures before the election, but this request is now moot."
He is one of five candidates trying to succeed Sepp Blatter, whose presidency ended on Dec. 21 when he was banned for eight years by FIFA's ethics committee.
Sheikh Salman Bin Ebrahim Al Khalifa, Gianni Infantino, Tokyo Sexwale and Jerome Champagne are the other four candidates vying for the position, which is set to be decided in Zurich this week.
Champagne also had a complaint rejected on Tuesday against a decision by the three-member FIFA election panel. He objected after FIFA approved election hall passes for 20 additional UEFA staff and seven from the AFC. Champagne said that gave the confederations an unfair advantage with greater lobbying power.
In a written reply to Champagne seen by The Associated Press, election panel chairman Domenico Scala said the extra accreditations were "perfectly in line with the relevant and consistent FIFA practice" for continental bodies.
