Thats wrong Harry,
A Technical Directive IS NOT the technical regulations!!!! Thats the point I am trying to make.
You would be brave or have to have good reason to go against a technical directive, but it is more Charlies opinion as FIA front man of the technical regulation and is openly able to be contested.; as RBR are doing.
"Technical regulations" say "Fuel mass flow must not exceed 100kg/h "
Technical Directives are NOT BINDING and issued as means of clarifications. The International Court of Appeals will have the final say, but they will firstly look at the Technical Regulations and see if there is ample compliance with those in consultation with the regulations.
"Opinions" given by the FIA outside of the Technical Regulations are meant for guidance and they are only guidance they do not constitute part of the Technical Regulations. A Technical Directive may come from the FIA but up to the ICA to see if RBR were in compliance with the Technical Regulations, not a technical directive
