This decision in a bench ruling has some interesting issues on what should be disclosed in discovery. First, it is important to not fail to list the witnesses that you will call at trial when answering interrogatories. Hanging back to the last minute may mean the witness will be barred from testifying. There was more to this than just delay but that is still a point worth remembering.
Second, the scope of expert discovery may well include notes and work papers of everyone who is on the team assisting the expert witness and will certainly include prior studies the expert has done on the same subject matter for other clients. This points out the need to be careful in setting up the expert’s team and in selecting the expert.
