In re Laura L.

Laura protests that a Juvenile Court judge’s order, committing her involuntarily to a mental health facility pursuant to G. L. c. 123, § 12(e),2 was invalid because state*854ments that she made to a court-appointed psychologist were admitted in evidence without a knowing Lamb waiver. See Commonwealth v. Lamb, 365 Mass. 265, 270 (1974).3 We conclude that the judge’s failure to make any inquiry or findings on the Lamb issue was error, amounting to a substantial risk of a miscarriage of justice and, therefore, vacate the order of commitment.

This, in outline, is the tortured history of the dispute.…
