Questione giuridica chiave
Whether the penalty clause required prior default notice or delay before it could be claimed
Decisione estratta
No prior default notice was required because the clause concerned a true abstention obligation; breach and maturity of the penalty claim sufficed.
Motivazione estratta
The site-retention undertaking was an obligation not to relocate the site, not an active performance duty. For non-performance of such an abstention duty, default notice was unnecessary.
