who is a gazzeted officer?

Article 309 of the Constitution of India (Part XIV Services under the Union and States) specifies the recruitment and service conditions of persons serving under the Union and States.
Under this power, names of the Class I officers either recruited or promoted by UPSC, along with legal notices, amendments to recruitment rules, etc are published in the Official Gazette of India. And all such officers listed in the gazette are therefore called Gazetted Officers.
 

Thank you Mr Vishal and Ram Mohan.

query solved.

thanks again.

But I partially disagree wtih Mr AV Vishal.  One does not hve to be class-I to be gazetted. I was gazetted much before being class-I
