"To the leader" or "to the manager."

Here, 'руководителю' is in the dative case, indicating the recipient of the action, i.e., the person to whom the documents are handed.

In this example, 'руководителю' is again in the dative case, describing the person to whom the letter is addressed, showing direction or intended recipient.

This sentence uses 'руководителю' in the dative case, representing the individual to whom the explanation should be directed.
