The Fifth Court of Appeals in Dallas ruled for a wireless-infrastructure tenant against the successor owner of the shuttered Collin Creek Mall, holding the landlord could not use an impossibility or impracticability defense to excuse its termination of a lease it had voluntarily assumed and performed under for months. ATC Indoor DAS LLC, which installed and maintained distributed antenna equipment serving AT&T and Verizon inside the mall, sued after MM CCM 48M Leasing, LLC -- which bought the failing mall and assumed the host lease -- terminated the agreement and gave ATC 30 days to remove its equipment once the mall closed.

Why it matters

Confirms that a successor purchaser who voluntarily assumes a lease and performs under it cannot later invoke changed market conditions -- here, a mall's total collapse and closure -- as an excuse to walk away from that lease altogether; 'merely shifting market conditions,' the court held, do not excuse contractual performance. Owners acquiring distressed retail assets encumbered by specialty tenant leases (wireless infrastructure, telecom, signage, and similar arrangements that survive an anchor's departure) should treat assumption of those leases as a binding commitment that a later decision to close or redevelop the property does not automatically unwind.
