Why EITS? The controller hasn't done anything wrong, just may be asked for something that is no longer achievable due to reducing the speed after the aircraft had begun descent. It hasn't been stated if the controller reissued the level by TELTU instruction, and if they did then a pilot reply saying that isn't possible is acceptable. If the speed hadn't been reduced then I'd have fully expected the aircraft to still comply with the TELTU restriction even if I had vectored the aircraft all over the sky and stopped off at an intermediate level, as long as the descent had been continuous. The STAR says "expect FL130 level TELTU", until being cleared either beyond TELTU or below FL130, this should always be expected unless information is received otherwise.
There was an argument on here several years back about vectoring and STARs, some trying to embellish the "a new clearance automatically cancels the previous unless reiterated" saying that as soon as a vector is given, the STAR is automatically cancelled. We are all in this together and that would be a very dangerous game to play!
