You can only use WP when discussing a settlement.
You can't admit liability via WP. It cannot be used as a device to hide evidence.
The solicitor for the defendant writes a letter to the plaintiffs solicitor that more or less says the case been brought against the defendant should be brought against another party. the letter was written WP. this is clearly not a dispute or trying to reach a settlement. i think the solicitor should answer the letter plus the letter should be used in court. does someone else have an opinion on this? i would like to hear it.
