 In Taylor , a series of deliberate discovery violations by the defense counsel at trial led the trial judge to block attempts at postponing proceedings to allow a further undisclosed defense witness the chance to testify ; the judge had held that there must be some sanction against the defense for their failure to disclose witnesses earlier in the case . A divided Court upheld the trial judge 's preclusion of the witness , adding a new framework for balancing a defendant 's right to a robust defense with a series of other factors . Namely , the new framework required looking at the state 's interest in " efficient " justice , the state 's interest in excluding evidence lacking integrity , the state 's interest in a strong judicial authority with followed rules , and the prosecution interest in avoiding prejudice due to a defendant 's discovery violation .
