Thanks HD, yes, I should have said that I was a fully rated radar controller providing an approach radar control service.
I was trying to illustrate the principle that a controller can use radar-derived information without actually providing a radar service or - in the right circumstances - a radar qualification.
And I think ICAO is rather vague on the qualifications that an ADC need to use radar, passing the buck to the national authority to set the rules. And unfortunately it sounds like male's national authority hasn't clarified what should happen locally.
