No Suttas - but there is this from Thanissaro Bhikkhu on:Being Judicious, not Judgmental http://www.dhammatalks.org/Archive/Writ ... s%20vs.pdf
and, a little more on a different tangent from him - about judging others:
''Of course, many people in our society are uncomfortable with the notion of right and wrong--especially in the area of religion.
I don't think it's so much that they are uncomfortable with the notion of right and wrong. It's just that they've shifted their reference points. Being judgmental is now wrong; being non-judgmental is right. This, I think, comes from two factors. One is that we're tired of fervid monotheists who demonize anyone who differs from their view of The One True Way. We've seen the harm that comes from sectarian religious strife, and it's obviously pointless. So we want to avoid it at all costs. The other factor is that we ourselves have been subject to evaluation all of our lives, some of it pretty unfair—in school, at work, in our relationships—so when we come to retreats we want respite.
This becomes a problem, though, when people confuse being judgmental with the act of exercising judgment. And again, the difference is a question of skill. Being judgmental—hypercritical, quick to dismiss the opinions of others—is obviously unskillful. But in our rush not to be judgmental, we can't abandon our critical abilities, our powers of judgment. We have to learn how to use them skillfully. It's all very fine not to pass judgment when you're on the sidelines of an issue and don't want to get involved. But here we're all out on the playing field, facing aging, illness, and death. Our skill in exercising judgment is going to make all the difference in whether we win or lose. The team we're facing has never been taught to be uncritical. They play hard, and they play for keeps
The Buddha himself was quite critical of teachers who wasted their time—and that of their students—by asking the wrong questions. He was especially critical of those who misunderstood the nature of karma, because how we comprehend the power of our actions is what will make all the difference in how skillfully we choose to think and act. So refraining from judgment is not the answer to the question of how we face the differing teachings we find available. In fact, a knee-jerk nonjudgmental stance can often be a very unskillful way of passing judgment.'''http://www.urbandharma.org/udharma3/interview1.html
