Or what is the sense of publishing the details of the lawyer?
I have important details for your case that your lawyer should be aware of.
How do I sabotaging my own case?
It would be very damaging to your case if you conceal details from your lawyer and those details are brought up by your opponent in court.
That is, unless you have no lawyer and no case, which obviously would make it very difficult for you to provide the contact info of the nonexistent lawyer, and would also make it very difficult to have any problems in the non-existent court case.
