You are stating that he has been explicitly banned under INA Sec. 212(a)(6)(C)(i)? A ban under that provision, "Any alien who, by fraud or willfully misrepresenting a material fact, seeks to procure (or has sought to procure or has procured) a visa, other documentation, or admission into the United States or other benefit provided under this Act is inadmissible", is permanent. He can't enter without successfully obtaining a waiver of his inadmissibility. See INA Sec. 212(i).
This is one of the reasons we repeatedly tell people, "Don't lie to the USCIS".
