Is a café liable when a customer slips on a wet floor it knew about but hadn’t mopped?

Short answer

Likely yes, if the risk was foreseeable and a reasonable café would have mopped or signed the area. Duty is established by the relationship; breach is the contested question (Civil Liability Act 2002 (NSW) s 5B). A court asks whether the risk was foreseeable and not insignificant, and what a reasonable person would have done (Wyong Shire Council v Shirt (1980) 146 CLR 40 at 47–48).

Causation and scope are separate: the customer must show the omission caused the fall, and that the kind of harm is within the scope of the duty (Wallace v Kam (2013) 250 CLR 375 at 383).

The difference

Most legal AI asks you to trust it. Lexi shows the paragraph.

A citation is only useful if it tells you where to look. Lexi is built to give you the paragraph, not the vibe.

  • 01

    A pinpoint for every proposition

    A paragraph for a case, a section for an Act. Not a case name with no page.

  • 02

    AGLC4, because that is what gets marked

    The citation standard used by Australian courts, journals and law schools.

  • 03

    Limits stated, not hidden

    Where a point cannot be verified, the answer says so instead of sounding confident.
