Depends whether a 16 year old is considered mature enough in Australia ! Regardless of which - they certainly shouldn't be interviewed without legal representation !
If the alleged abuse is about the parent then yes.
yes
This is not a question. A question must be asked in order to receive an answer.
Yes, but it's a better idea for a lawyer to be present.
Teachers and administrators can question kids. If a police officer is present or performing the questioning, a child has a right to both an attorney and their parent. Check your school district''s webpage and your state's code. For example, google "Michigan State Code, interrogation of a minor" and see what the age and rules are for your state.
No, a parent must be present.
Yes but it depends if it involves the parent
If the question is an incriminating one then absolutely not. Example: Did you break the window next door? If the question isn't incriminating then yes. Example: Did you see where the robber ran?
Yes a minor can be arrested. Once they are confirmed to be a minor, an advocate will be appointed to protect their rights.
Police can question anyone if they have the proper authority (e.g. warrant), but a parent or guardian is authorized to be present during questioning of a child.
Did the crime just occur? Is the juvenile stopped on the street? Is the juvenile in custody? Unable to answer without more specific information about the event. (????)
At this age you are considered an adult . Your parents do not have to be present. They no longer are responsible for you.
