This is a compilation of Path Breaking Judgments On Indian Police, from the Bureau Of Police Research And Development (http://bprd.gov.in). It is fairly comprehensive and the same set of judgments are hosted by the AP CID. I only wish they made more of an effort on presenting the document. There are blank pages in between and some of the names of the petitioners and respondents are spelled incorrectly. I tried to clean up as much as I could.
Here is the documents: Path Breaking Judgments On Indian Police
