Getting the Opinion In:
The Daubert-Joiner-Kumho Tests.

         By Leonard Bucklin

"Here in the most compact form possible, is practical advice on what you and the expert need to know and do:

A good expert witness should be prepared to withstand questioning under either the Frye standards, still used in many states, or those applied under the Daubert / Kumho tests, used in the federal courts and many states. An expert who is knowledgeable about, and comfortable with, the legal aspects of being an expert witness becomes a more effective and therefore more valuable expert. An attorney who does not get his expert's testimony into evidence is probably going to lose the case!"
