Which one is right, 'which were' or 'which are'?

which are

Yes, use the present tense throughout the sentence.

Both sentences are grammatically correct, but the difference lies in the tense of the verb used.

1. "Judge: a person who is trained to hear and decide cases which were brought before a court of law."
In this sentence, the verb "were" indicates the past tense, implying that the cases were already brought before a court of law in the past. This sentence refers to judges who have already dealt with such cases.

2. "Judge: a person who is trained to hear and decide cases which are brought before a court of law."
In this sentence, the verb "are" indicates the present tense, suggesting that the cases are currently being brought before a court of law. This sentence refers to judges who are currently dealing with or have the responsibility to deal with such cases.

Therefore, the choice between "which were" or "which are" depends on the intended timeframe of the statement and the context in which it is being used.
