NY S09110

Shifts burden of proof in harmless error analysis so the party claiming an error was harmless must demonstrate it was harmless beyond a reasonable doubt, rather than the defendant proving harm.

Requires appellate courts to consider errors not raised at trial if the defendant asserts the failure to protest resulted from ineffective assistance of counsel or if the error may have contributed to the jury verdict.

Mandates appellate courts record the race, ethnicity, national origin, age, and gender identity of appellants when deeming errors to be technical and not affecting substantial rights.

Requires the chief administrator to include recorded demographic data in annual reports to the legislature and governor, disaggregated by county, and to publish this information on the office of court administration website in machine-readable format updated yearly.

Takes effect immediately and applies to all pending appeals and appeals filed on or after the effective date.
