Questions & Answers about Адвокат тоже хочет допросить этого человека в суде.
Why does "this person" translate to этого человека instead of этот человек?
It is the direct object of the verb допросить, so it must be in the Accusative case. Because человек (person) is an animate masculine noun, its Accusative form looks exactly like its Genitive form (человека). The demonstrative pronoun этот (this) must match, becoming этого.
Why do we use the perfective verb допросить here instead of the imperfective допрашивать?
The lawyer wants to conduct a single, complete interrogation of this person to achieve a result. If the sentence implied interrogating the person repeatedly over a long period, or focused purely on the ongoing process of questioning them without a focus on completion, you would use the imperfective допрашивать.
Could I use также instead of тоже to mean "also" here?
Тоже is the most natural choice because it groups the lawyer with someone else: someone else wants to interrogate this person, and the lawyer wants to do it too. Также is generally used to add a new action or item to a list, for example: the lawyer wants to review the documents and also interrogate this person.
Could I say на суде instead of в суде?
You can, but the meaning shifts slightly. В суде focuses on the physical location or the institution (in the courthouse or in the court of law). На суде refers more to the event itself, meaning "at the trial" or "during the hearing."
