Lady Justice

The time-honoured symbol of justice in the West is the Lady of Justice (adapted from Greek and Roman mythology) depicted as a blind-folded woman with a scale in one hand and a sword in the other. This stands for equality in the dispensation of justice without favor or prejudice.
Lady Justice, who dates back to the ancient Greek goddess Themis, is the symbol for fair and equal justice. No matter how she is depicted, her eyes are always covered so she can't be influenced by the person being judged and so does not fall to prejudice.
