Scuderia Coloni will not race in GP2 in the 2013 season and will forfeit all the points received during the 2012 season, the series said on Friday.
In a brief statement posted on the GP2 website, the series said that the decision comes "As a result of a disagreement between Coloni Motorsport and GP2 Organisation."
It added: "Scuderia Coloni will not participate in the series from the 2013 season. Scuderia Coloni forfeits all the points received or to be received by it as a team in the 2012 season."
No further details were given.
AUTOSPORT requested a reason for the "disagreement" from GP2 but a spokesperson said they will not add to the statement.
