The European Court of Human Rights rejected the appeals made to them, for the French security forces not to use grenades against civilians shows double standards.
According to the European Court of Human Rights press release from December 18, 2018, on December 14, 2018, the Court received a lawyer's request to order, as soon as possible, provisional measures putting an end to inhuman and degrading treatment and violations of the right to life suffered by participants of the "yellow-vest" protests. The request was to urge France to temporarily ban the use of defence bullet launchers, as well as incapacitating liquids by the police.
The request was made in relation to case Kazoua et al. vs France, registered under number 58803/18, a case alleging French police violence by 5 plaintiffs.
The request was forwarded to a Chamber of the Court, pursuant to Rule 39 of the Rules, which rejected the request for an interim measure concerning the security forces’ use of flash-balls and incapacitating liquids. The Court grants the requests for interim measures only exceptionally, where the applicants would be exposed - in the absence of such measures - to a real risk of irreparable damage.
This means that the ECHR did not rule on the case as such, neither did it in any way anticipate subsequent decisions on the admissibility or merits of the case before it.
