What does this sentence mean?

Hello, everyone.

I am confused as to the meaning of the following part in bold.

An Advocate General sits on the bench with the judges and once the parties have given their views, he will deliver his opinion, which can not be deliberated upon by the parties.

I looked up the definition of deliberate in my dictionary.

I don't understand why an Advocate General's opinion can be considered by the parties. Surely no one can be so wise that he always comes up with things other people failed to consider.

There must be something wrong with my interpretation.

I'd be so glad to hear your opinions.

Many thanks

Which country's legal system are we considering here?

Hello, Rove_KE

Thanks for you reply.

I am reading a book called Essential English Legal System. But the text comes under the title Procedure of the European Court of Justice.

Here's the full context:

The court sits in Luxembourg and consists of 13 judges and six Advocate Generals. The procedure is different from an English court. An Advocate General sits on the bench with the judges and once the parties have given their views, he will deliver his opinion, which can not be deliberated upon by the parties. Advocate Generals are responsible for investigating the issue placed before the court. A report is compiled and recommendations made, which the court will consider. The court is not bound by the report or recommendations made by the Advocate Generals; it can act upon them or reject them as it chooses.

Many thanks

Do you mean the above?
I don't know that system. No one can stop someone deliberating on something. However, the system could make any further deliberation irrelevant to the outcome.
