What Is the Scope of Expert Discovery in Kansas?
In Kansas, the scope of expert discovery is largely guided by the Kansas Statutes Annotated (K.S.A.) 60-226(b)(6), which outlines a disclosure approach akin to the Federal Rule of Civil Procedure 26(b)(4). Under this statute, parties are required to disclose affirmatively the identity of any expert witness they intend to call at trial. This includes detailing the subject matter of the expert's testimony, the substance of the facts and opinions, and a summary of the grounds for each opinion.
- Permitted Discovery: Kansas permits discovery of expert information through affirmative disclosures, encompassing both identity and substantive opinions.
- Limits: Draft expert witness report disclosures and attorney–expert communications are generally protected, except when they concern compensation or facts and assumptions provided by counsel (K.S.A. 60-226(b)(5)(B)).
Timing and Procedure for Expert Discovery in Kansas
Expert discovery in Kansas occurs within a specific timeline, often dictated by court orders or scheduling requirements.
- Timeline: Expert discovery typically transpires after initial disclosures but before trial, with specific deadlines set by the court.
- Procedural Steps: Parties must serve written expert disclosures, which should be signed and filed with the court. Depositions of experts expected to testify are permissible under K.S.A. 60-226(b)(5)(A).
- Supplementation: According to K.S.A. 60-226(e), parties must supplement their expert disclosures if they discover the information is incomplete or incorrect.
What Methods of Expert Discovery Are Permitted in Kansas?
Kansas allows several methods for expert discovery, primarily focusing on testifying experts rather than consulting ones.
- Permitted Methods: Depositions, written interrogatories, and document requests are standard methods for expert discovery. However, non-testifying consulting experts are shielded from discovery unless exceptional circumstances are demonstrated (K.S.A. 60-226(b)(5)(D)).
- Distinctions: Discovery is mainly confined to testifying experts, with consulting experts remaining largely protected except under specific conditions.
Limits on Discovery of Expert Materials and Communications
Kansas imposes specific limits on the discovery of materials and communications involving experts to maintain privilege and work-product protections.
- Protected Materials: Draft expert reports and communications between attorneys and experts are protected from discovery, except for communications about compensation or counsel-provided facts and assumptions (K.S.A. 60-226(b)(5)(B)).
- Exceptions: Exceptions to these protections may include materials related to bias or reliance materials.
Consequences for Noncompliance or Discovery Violations
Failure to adhere to expert discovery rules in Kansas can result in significant sanctions or remedies under K.S.A. 60-237.
- Potential Consequences:
- Exclusion of expert testimony
- Monetary sanctions
- Continuances or other remedial actions
- Enforcement: Courts in Kansas enforce these rules stringently, ensuring compliance through various sanctions.
