Outcomes
Limited disclosure of firmware ordered to assist claimants' sample selection.
Necessary and proportionate given claimants' rational explanation and consistency with Mercedes litigation; addresses information asymmetry.
Number of firmware strings reduced to 100 (providing ~70% coverage) from claimants' request of 150.
Proportionate considering the coverage achieved and workload.
Specific timeframes set for firmware disclosure by each defendant, with flexibility for adjustments based on further evidence.
Balances the needs of all parties, considering the specific circumstances of each defendant.
Number of samples set at 'up to 12' per defendant or defendant pair, encouraging further discussion amongst parties.
Balances the need for a security blanket against settlement with practical considerations for trial management.
