Although a California Court may properly sanction a non-party insurance carrier who possesses the authority to settle litigation for its failure to participate in a mandatory settlement conference, there is no statutory (nor inherent) authority given the Court to sanction the carrier or a party for its purported failure to negotiate in "good faith."  As the Court in Vidrio v. Hernandez (2d DCA) explained today:

In sum, even were we to agree with the trial court's assessment of the conduct of counsel and the [insurance] adjuster, the failure to increase a settlement offer or to otherwise participate meaningfully in settlement negotiations violates no rule of court and is not a proper basis for an award of sanctions.11 (See, e.g., Triplett v. Farmers Ins. Exchange (1994) 24 Cal.App.4th 1415, 1424 [“[w]e eschew any notion that a court may effectively force an unwilling party to settle by raising the specter of a post hoc determination that failure to do so will be evidence of failure to participate in good faith”]; Sigala v. Anaheim City School Dist., supra, 15 Cal.App.4th at p. 669 [“„[a] court may not compel a litigant to settle a case, but it may direct him to engage personally in settlement negotiations, provided the conditions for such negotiations are otherwise reasonable‟”].) [Defendant] filed an appropriate settlement conference statement; her lawyer and Mercury [the insurance carrier] attended the conference and participated in it. While the trial court‟s frustration at the parties‟ lack of movement is understandable, no more was required.
