Under CCP art. 42.18 §8(d), when sentences involve the stacking of pre- and post-1987 offenses, those sentences should be treated as one
unit for the purpose of determining when a defendant is eligible for
release on mandatory supervision for all sentences that are eligible
for mandatory supervision. Under CCP art. 42.18 §8(c), a release date
for mandatory supervision for all the mandatory-supervision-eligible
sentences would be calculated as a unit, and then add the length of any
mandatory-supervision-ineligible sentences to arrive at a final
mandatory supervision release date.
