Absentee voters at Tuesday's meeting at Biggin Hill prevented the F1 Commission from passing a vote which agreed on cost, availability, noise and performance resolutions accepted earlier in the day by the Strategy Group.
As a result, 2017 engine regulations and a few other changes under consideration could not be sent to the World Motor Sport Council for ratification before the official deadline set for Saturday, April 30.
It has now been decided that members of the F1 Commission - which include FOM, the FIA, teams, sponsors and promoters - have until this Friday to cast a vote, by fax.
Should the process be completed and the resolutions get a final sign-off, power unit regulations would effectively be set in stone until 2020, which in turn would end any hope of introducing an independent engine concept as hoped for, and indeed promoted, by F1 supremo Bernie Ecclestone.
