reproachable

This term carries a heavy moral weight, suggesting that a person's actions have breached a standard of ethics or professional conduct. It is more formal than saying someone is "blameworthy" and often appears in legal, ecclesiastical, or high-level administrative contexts where a formal judgment of character is being made.

While it describes a negative quality, the word is frequently encountered in its negated form, "irreproachable," to describe a flawless reputation. When used in the affirmative, it implies a specific vulnerability to criticism rather than a general state of being bad, focusing on the justifiability of the blame.
