## Facts

- Two sets of plaintiffs, residing in Norway and Sweden, were the wives and children of decedents who received Bjork–Shiley prosthetic heart valves implanted in their home countries.
- Shiley Incorporated, a California corporation, designed and manufactured the valves in California; its parent company was also sued.
- The valves allegedly failed abroad, causing the patients’ deaths.
- Plaintiffs filed suit in California alleging negligence, strict products liability, breach of warranty, fraud, loss of consortium, and (in one action) negligent infliction of emotional distress.
- Defendants moved under California Code of Civil Procedure § 410.30 to dismiss or stay on forum non conveniens grounds, asserting Norway and Sweden were more appropriate because plaintiffs, medical care, records, treating physicians, and key proof were located there.
- The trial court found Norway and Sweden to be suitable alternative forums and stayed (not dismissed) the California actions, conditioned on defendants’ submission to jurisdiction abroad and related terms to permit litigation there.
- The Court of Appeal affirmed; the California Supreme Court granted review to address standards applicable when foreign plaintiffs sue a California corporation in California courts.

## Issues

1. What standards govern a § 410.30 forum non conveniens motion when foreign plaintiffs sue a California corporation in California?
2. Did the trial court abuse its discretion by granting a conditional stay in favor of Norway and Sweden?

## Decision

- The California Supreme Court unanimously held the trial court did not abuse its discretion in staying the actions on forum non conveniens grounds.
- The court approved a two-step approach: determine whether an adequate alternative forum exists, then balance private and public interest factors.
- Norway and Sweden were suitable alternative forums because defendants agreed to submit to jurisdiction there and remedies were available, even if less favorable than in California.
- Private interest factors favored litigation abroad because medical treatment, records, causation evidence, damages proof, and many witnesses were located in Norway and Sweden.
- Public interest factors supported the stay given the foreign locus of injury and stronger foreign regulatory and adjudicatory interests, and the burden on California courts and juries.
- Plaintiffs’ foreign residence reduced the deference owed to their choice of a California forum.
- The judgment affirming the conditional stay was affirmed.

## Legal Principles

- Under Code of Civil Procedure § 410.30, a court may stay or dismiss an action in the interests of substantial justice when trial in another forum is more appropriate.
- Forum non conveniens analysis proceeds in two steps: (1) identify a suitable alternative forum (defendant amenable to process and the dispute can be litigated there), then (2) weigh private and public interest factors.
- An alternative forum is not unsuitable merely because its procedures or damages rules are less favorable than California’s.
- A foreign plaintiff’s choice of a California forum receives less deference than a California resident’s choice, though it remains a factor.
- Appellate review is for abuse of discretion; a trial court’s balancing is upheld if it applies the correct standards and reaches a reasonable result.
- A conditional stay, rather than dismissal, is an appropriate mechanism to ensure the alternative forum is actually available (e.g., through consent to jurisdiction and related conditions).

## Conclusion

The court upheld a conditional forum non conveniens stay, clarifying that when foreign plaintiffs sue a California manufacturer over injuries occurring abroad, California courts may defer to suitable foreign forums after confirming availability and reasonably balancing private and public interest factors, with reduced weight given to the foreign plaintiffs’ forum choice.
