A single Judge of AP High Court held that,

From Paras 5, 6 and 7,

5. In view of the fact that the 2nd respondent has been issuing such certificates to citizens staying abroad, the 2nd respondent cannot take the stand that since it is a voluntary service, there cannot be any direction to the 2nd respondent to issue or not to issue such certificates.
6. In the circumstances, this writ petition is disposed of directing the 2nd respondent to issue a police clearance certificate after recording all the cases filed against the petitioner which have come to the notice of the 2nd respondent. This can be done only after the 3rd respondent has informed the 2nd respondent in writing about the case, which is pending before the 3rd respondent.
7. Accordingly, the 3rd respondent is granted two weeks time to forward all the details of the cases against the petitioner available with the 3rd respondent. Upon receipt of such information, the 2nd respondent, within four weeks thereafter, shall issue a certificate as mentioned above. There shall be no order as to costs.
