The actual document says:
Per the Marvel Cinematic Universe Wiki, The Sokovia Accords are a set of internationally ratified legal documents that provide regulation and frame-working for the military/law enforcement deployment of enhanced individuals, particularly the Avengers, orchestrated by world governments.

Captain America: Civil War drops in theaters on May 6th, 2016.
