Bayer Bioscience N.V. v Deltapine Australia Ltd (No 2) [2007] FCA 411

Leave to amend was refused because Deltapine provided no evidence, even on a hearsay basis, as to the merits of the proposed invalidity allegation; the allegations were broad, vague and concerned events about 20 years earlier; there was no evidence explaining the delay; and the asserted assignments supported an inference that the alleged claim was within Deltapine's or its associates' knowledge almost a year earlier.
