Key legal question
How to interpret the rent escalation clause in the ground lease contract
Extracted holding
The clause required the specific condition of shop opening hours being allowed from 06:00 to 21:00, seven days a week including holidays; it did not provide for a proportional increase in case of lesser liberalization.
Extracted reasoning
The wording was clear and twice repeated. The contractual context showed the parties regulated only one specific change in circumstances. Under the reliance principle, the respondent could trust that a pro rata increase would have been expressly stated if intended.
