Grading rubric
Criteria and grader verdict (showcase run)
States that in the "Entry for Repairs and Inspection" clausee, California Civil Code §1954 requires reasonable notice for non-emergency entries
FailEvidence: The response says Section 6.B allows entry “at all times without notice” and recommends narrowing to “reasonable prior notice except emergencies.” Assessment: The criterion requires stating that California Civil Code §1954 requires reasonable notice for non-emergency entries. The response does not mention Civil Code §1954 or frame the requirement under that statute, so it fails.
States that in the "Entry for Repairs and Inspection" clause, California Civil Code § 1668 prohibits waiving any remedies arising from the Lessor’s own negligence
FailEvidence: For Section 6.B, the response says the clause likely cannot eliminate remedies for “unlawful or willful conduct by Lessor.” It cites Civil Code §1668 only in the Section 7 discussion. Assessment: The criterion requires stating that, in the Entry for Repairs and Inspection clause, §1668 prohibits waiving remedies arising from the Lessor’s own negligence. The response does not state this for the entry clause and omits lessor negligence in that context, so it fails.
States that in the "Indemnification" section, California Civil Code § 1668 disallows the release of all leasor liability to the extent it covers the leasor's own negligence
FailEvidence: The response states Section 7 is unenforceable to the extent it releases MGR from “fraud, willful misconduct, statutory/building-code violations, or other violations of law,” citing §1668. Assessment: The criterion requires stating that §1668 disallows the release of all lessor liability to the extent it covers the lessor’s own negligence. The response does not clearly say the lessor’s own negligence is covered by the unenforceable release, so it fails.
States that California Civil Code Civil 1654 requires that the contradictory "sole and absolute discretion" and ""may not be unreasonably withheld" standards in the Assignment and Subletting section be interpreted against the party who drafted the contract
FailEvidence: The response identifies conflicting Section 8 standards and says California law construes ambiguity “in favor of transferability,” citing Carma Developers, and that ambiguity should be resolved “in the tenant’s favor.” Assessment: The criterion specifically requires stating that Civil Code §1654 requires the contradiction to be interpreted against the drafter. The response does not mention §1654 or interpretation against the drafter, so it fails.
States that in the Assignment and Subletting section's Consent Required clause, the "sole and absolute discretion" standard for landlord's consent will be unenforceable per California Civil Code Civil 1654
FailEvidence: The response says the “sole and absolute discretion” language is “likely unenforceable if MGR tries to use it to override” the later reasonableness standard, based on ambiguity/transferability. Assessment: The criterion requires stating that the Consent Required clause’s “sole and absolute discretion” standard will be unenforceable per Civil Code §1654. Because the response does not invoke §1654 as the basis, it fails.
