◆ ◆ The Wire takeaway
If you're building AI legal research or brief-writing tools, your product is now your customer's liability. Courts have decided that 'I used AI' is not a defence—the person filing bears the cost of verifying every citation, which means your tool either embeds verification or it doesn't ship to lawyers at all.
