Can a party be found to have waived their contractual right to arbitrate by engaging in dilatory conduct in an arbitration proceeding?

The California case on which respondents primarily rely for their waiver argument, Weisman v. Johnson, supra, 133 Cal.App.3d at page 295, 183 Cal.Rptr. 792, does not extend so far as to authorize a finding of waiver in this case. [41 Cal.App.4th 173] Indeed, there is no authority under either California or federal law ²¹ to support a court in ruling that a party has "waived" its contractual right to arbitrate by engaging in dilatory conduct in a pending arbitration proceeding.
