Lawyers response
The lawyers can only act on their clients instructions. If the client is not interested in any further action or realizes that they have a weak case, the lawyer cannot do any thing further.
Honesty with lawyers
It is important to be honest with your lawyer.  If you tell your lawyer lies, if the truth is discovered at a later date, it can be embarrassing and cause unnecessary problems. It also makes it difficult for the lawyer to defend the client.
