JUDICIAL POWER PLAY: The Limits of Judicial Power and Public Entity Liability Addressed in Quigley v. Garden Valley Fire Protection District

Set within in a classic constitutional power struggle between the legislature and the judiciary, the 2019 California Supreme Court opinion in Quigley v.

Opening the Floodgates: 9th Circuit Court of Appeals Holds Dynamex ABC Test for Independent Contractor Status Applies Retroactively

Last year, the California Supreme Court announced a new standard, known as the “ABC” test for determining whether a worker is an employee or independent contractor in wage and hour cases.  (Dynamex Ops. W. Inc. v. Superior Court (2018) 4 Cal. 5th 903). Two weeks ago, the Ninth Circuit Court of Appeals held the Dynamex test applies retroactively in Vasquez v. Jan-Pro Franchising International, Inc. (2019 WL 1945001). As discussed below, the Vasquez decision could have far-reaching economic implications.

Supreme Court Confirms Evidence of Industry Custom and Practice May Be Used in Product Design Defect Cases

The California Supreme Court recently upheld a Court of Appeal decision which allows evidence of industry practice in certain product design defect cases.  (Kim v. Toyota Motor Corp. (2018) 6 Cal. 5th 21).  The product at issue in Kim was a 2005 Toyota Tundra which was not equipped with vehicle stability control (“VSC”).  Specifically, the high court held in an appropriate case a jury may consider whether a product is as safe, or safer, than any product on the market in evaluating whether on balance the product’s design is defective.  As demonstrated below, the Kim decision is significant for multiple reasons. It allows a product manufacturer to embrace its design decisions based on free market economic realities. The decision further diffuses juror anger based on a plaintiff’s one-sided and misleading evidentiary slight-of-hand intended to paint the manufacturer as a danger to the community by disregarding consumer safety.

Expert Designation and Summary Judgment Practice: Is a Summary Judgment Declaration by a Retained Expert a Designation in California?

California’s Summary Judgment Statute (Code of Civil Procedure Section 437c) was designed to “penetrate evasive language and adept pleading and to ascertain, by means of affidavits, the presence or absence of triable issues of facts.”  (Preach v. Monter Rainbow (1993) 12 Cal. App. 4th 1441).   A situation which often comes up in practice arises when a party submits a declaration from an expert either in support of or in opposition to a summary judgment/adjudication motion.  Because a summary judgment motion is often filed well before the time for designation of experts provided by Code of Civil Procedure Section 2034, several significant procedural issues arise including (1) May the expert who gave the Declaration in support or opposition to the summary judgment motion be deposed? (2) If so, what is the scope of the deposition; and (3) Is the expert entitled to fees for testifying?  The Second District Court of Appeal case, St. Mary Medical Center v. Superior Court (1996) 50 Cal. App. 4th 1531, provides some guidance on these issues.

California Supreme Court Redefines Independent Contractor Test for Wage Orders


In a recent opinion, the California Supreme Court adopted a new test for determining whether a worker is an employee or independent contractor in certain contexts.  SeeDynamex Operations West v. Superior Court, (April 30, 2018) 4 Cal.5th 903, [232 Cal.Rptr.3d 1, 416 P. 3d 1]..  The Court adopted what is known as the “ABC” test used in other jurisdictions.  Under the test, a worker is an independent contractor only when the following are established: (A) the worker is free from the control and direction of the hirer in connection with the performance of the work, both under the contract for the performance of such work and in fact; (B) the worker performs work that is outside the usual course of the hiring entity’s business; and (C) the worker is customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed for the hiring entity. (Id. at p. 8).  It is important to note however, this new test is limited (at least for now) to the application of Wage Orders which define the term “employ” as “to engage, suffer, or permit to work.”
