Chalmers on the justification of phenomenal judgments

We seem to enjoy a very special kind of epistemic relation to our own conscious states. In The Conscious Mind (TCM), David Chalmers argues that our phenomenal judgements are fully-justified or certain because we are acquainted with the phenomenal states that are the objects of such judgements. Chalmers holds that the acquaintance account of phenomenal justification is superior to reliabilist accounts of how it is that our PJs are justified, because it alone can underwrite the certainty of our phenomenal judgements. I argue that Chalmers is unable to sustain this claim.
