Key legal question
Whether B.________ Sàrl had standing to lodge a complaint against the office's refusal to stay the auction.
Extracted holding
Yes. As tenant of the property and holder of a contractual set-off right, it was affected at least in its factual interests and risked economic harm.
Extracted reasoning
Under Art. 17 LP, standing exists for anyone injured or threatened in legally protected interests, or at least affected in factual interests, by enforcement measures. B.________ Sàrl was directly exposed to adverse economic consequences from the auction.
