During peer review process, as we all know we modify our articles based on the reviewers comment that we get. But when we submit our revised version of the manuscript, is it necessary that the same reviewers- who participated in the first review based on whose comment that the revised version is prepared reviews the manuscript 2nd time also. This happened to me. One of the article, submitted to a good reputed journal of my discipline. In the first review, I got comments from three reviewer. Based on the comment I revised my manuscript and submitted. In the second review report, I got comments from two reviewer instead of three. There was co-relation of comments of one reviewer from the first review report (so can be guessed that the reviewer is same) but the comments from the 2nd reviewer were entirely new. The I prepared the 2nd revised version based on the 2nd review report, and submitted it. Now I got the 3rd review report, where I got some entirely new comments which didn't co-relate any way with the first and second review report.
If the same persons do not review the revised versions, then doesn't it violate the sole purpose of peer review also wasting a lot of valuable time. Can I ask more details about the process to the editor of the journal?
