Formula One teams have been told by the sport's governing body that the published 2010 regulations can only be changed if all, including the new entrants, agree.
The autosport.com website reported on Tuesday that International Automobile Federation (FIA) president Max Mosley had written to the teams pointing out the procedures laid down in the rules.
"Article 66 of the international sporting code states that no change can be made to the published regulations without the agreement of all confirmed entrants," Mosley wrote to the three new entrants plus Williams and Force India [ Images ].
"As a result, changes to the 2010 regulations require your agreement and consent".
The five are outside the eight-member Formula One Teams Association (FOTA).
All 13 teams were due to meet before this weekend's German Grand Prix [ Images ] at the Nuerburgring to discuss the 2010 regulations.
The three new teams, Campos Meta, U.S. F1 and Manor Grand Prix, all signed up to next year's championship when an optional 40 million-pound ($64.76 million) budget cap was planned.
The FOTA teams, led by champions Ferrari [ Images ], had threatened a breakaway series but dropped that when a deal was reached at a meeting of the FIA's world motor sport council in Paris last month.
The FIA said at the time that the rules for 2010 onwards would be the 2009 regulations "as well as further regulations agreed prior to 29 April 2009."
In return, the FOTA teams agreed to reduce the cost of competing in the championship to the level of the early 1990s within two years.
