HRT boss Colin Kolles has ruled out a protest at this weekend's Monaco Grand Prix over the use of off-throttle blown diffusers, with the FIA having promised him that it was looking into the matter.
Kolles wrote to FIA president Jean Todt over the Spanish GP weekend asking him for clarification about the situation - with the governing body having declared off-throttle use of the concepts illegal before changing its mind in the build-up to the Barcelona event.
That delay in sorting the situation had angered Kolles, who had suggested a few days ago that if the matter had not been resolved by this weekend's event then he would have no choice but to protest rival cars in a bid to get an answer.
However, with AUTOSPORT understanding that the FIA responded to Kolles making it clear that it was dealing with the matter as quickly as it could, the HRT team principal has said he is now willing to wait until the outcome of the Technical Working Group meeting on June 16.
That means a protest at Monaco this weekend, which could have overshadowed F1's blue-riband race, can now be ruled out.
Speaking to AUTOSPORT about the possible threat of a protest in Monaco, Kolles said: "I can rule it out now.
"We have been asked [by the FIA] to be on stand-by, and we trust that the FIA will react in the right way."
