Human Factors
During taxi for takeoff; notified by ACARS to contact Operations. Operations advise of HAZMAT on board without Captain being provided a Dangerous Goods Form and asked if I would take the information over the radio. I advised them that radio of the Dangerous Goods Form would not be possible and returned to gate. Upon gate arrival; advised hazmat in question was 3 cases of blood without 'proper documentation.' Cargo was eventually removed from aircraft. I'm not aware of the 'missing documentation' but suspect it was a Dangerous Goods Form for dry ice since blood is not Biological Substance. However; if any of these items are packaged in dry ice to keep them cool; dry ice is classified as a Dangerous Good and the Dangerous Goods Form is required. I was not informed if the packages included dry ice. Failure of policy and procedures.
A321 Captain reported a ground gate return to obtain missing hazmat documentation. Hazmat DG was removed from the aircraft.
