 Since 2006, an investigation is in progress at the brigade suppression of economic crime (OERD) on the electoral roles concerning about 30,000 voters who were sorted by ethnicity for the mayor of Asnières. Manuel Aeschlimann, termination three weeks of the elections would not be surprising. He further asserts that all files of the City Council have been declared to the CNIL and that it reserves the right to sue for slander.

The site Rue89 speaks of the "Judicial guerrilla that Aeschlimann lead against his opposition.
 Beginning in December 2007, the press leaked a report by the regional chamber of accounts Île-de-France. The City Council indicated that the documents were not those given to the regional chamber of accounts.
This document calls into question several aspects of the management of the town hall of Asnières-sur-Seine, in particular fiscal weaknesses and heavy indebtedness, excessive consumption of fuel for vehicles in city hall, a vehicle assigned to the wife of the Mayor, generous legal fee, claims" the "irregular appointment of a technical executive, managing the construction of a parking lot, and a "conflict of interest" of his deputy in real estate transactions. The report, delivered by the CRC in September 2007, did not get published before the 1 December deadline, making possible its publication until after the municipal elections of March 2008. The opposition accused the town hall of covering up the findings of this report.
 In the second round of the 2008 municipal elections, the socialists, MoDem (Mouvement Démocrate), and assorted right merged their tickets against him. This coalition was initiated by the joint petition against the non-publication of the report by the regional chamber of accounts. The coalition, led by Sébastien Pietrasanta, Josiane Fischer and Christian Leblond finally won the elections in March 2008, with 51.86% of the vote.
 The first municipal council of the newly elected team revealed that the report of the CRC which circulated during the campaign without being officially published was indeed the same as the one received by Manuel Aeschlimann in September 2007.
 In January 2009, he is condemned to 18 months in prison (suspended), an ineligibility of four years and a 20,000 euros fine for favoritism in a 1998 public procurement affair. In January 2011, the sentence is confirmed in appeal, the ineligibility being reduced to one year.
