No, no, no, no, no! Whoever taught you that is an idiot. Ask him to show you where it says that in the 7110.65.
The paragraph below from the 7110.65 provides you almost infinite latitude in determining that an aircraft should be treated as an emergency (ie, given priority), regardless of whether the pilot asks for it (or even wants it). The italics are mine:
"10-1-1. EMERGENCY DETERMINATIONS
d. Because of the infinite variety of possible emergency situations, specific procedures cannot be prescribed. However,
when you believe an emergency exists or is imminent, select and pursue a course of action which appears to be most appropriate under the circumstances and which most nearly conforms to the instructions in this manual."
In other words, if the guy in the Seminole tells you he's lost an engine, but is too stupid (or busy) to declare an emergency, then YOU do it-- by simply making him number one. No need to tell him you're doing it, just do it. If all goes well, that should be the end of it; if not, at least you did the best you could.
I once provided priority handling (causing short delays for a few airliners, and a go-around to another) which (I'm told) may have saved the life of a dog (inadvertently loaded as cargo, in a compartment that also had dry ice aboard). Not many pilots would declare an emergency in such a situation, for fear of repercussions-- but I could (and did) provide priority handling anyway, knowing that the worst that could happen is that some guy in the office wearing a tie might later say, "You did that for a dog?"
Nobody did, BTW-- and but if they had, I'd of said, "Yup, and proud of it."
No controller ever got in trouble for providing too much service, particularly to an aircraft that has
any sort of problem-- but plenty have had their judgement questioned in the aftermath of an accident, because they didn't provide enough.
