He sat in the Argentine Senate representing Santa Cruz Province in the majority block of the Front for Victory.
Banicevich served as Mayor of 28 de Noviembre in Santa Cruz and as a provincial state legislator between 2003 and 2007.
He was a member of the board of FOMICRUZ, the Santa Cruz state mining company.
On 10 April 2009, the sitting senator for Santa Cruz Judith Forstmann was killed in a road accident.
Banicevich's nomination as senator was somewhat controversial, both as he had previously been passed over in the order for replacements and because it would leave Santa Cruz as the only province with all-male representation.
