The Constitutional Council said in a statement that it was confirming a decision by France's electoral finance watchdog that Sarkozy had filed expenses of nearly 23 million euros, which exceeded the spending ceiling by 2.1 percent.
Because of this Sarkozy, who lost to Socialist Francois Hollande in the vote, is not eligible for the reimbursement of 47.5 per cent of total campaign spending he was due under election financing laws.
The former president has been implicated in a series of campaign funding scandals allegedly involving Liliane Bettencourt, France's richest woman, and former Libyan dictator Moamer Kadhafi. Sarkozy has denied any wrongdoing.
