[48] The admissibility or otherwise of evidence of subsequent conduct when a court or tribunal is seeking to determine the objective intent of the parties to an industrial instrument, contract, other agreement or document is by no means settled law in this country. Bearing that legal uncertainty in mind, I choose, in this case, not to rely upon the subsequent conduct of GrainCorp and NUW in seeking to ascertain the intent of the parties to the 2001 Agreement. Had I given such consideration, it is not likely to have been of great assistance - subsequent to the certification of the 2001 Agreement, GrainCorp did not replace two Bulk Grain Workers, but gave an explanation for not replacing Mr Markham that the Commission might reinstate him. Similarly, I draw no inferences, either positive or negative, from the fact that GrainCorp sought legal advice regarding the meaning and effect of clause 2 of Appendix B (s127 transcript, PN776-780, 789-794). While industrial instruments should not be read in an overly technical or legalistic manner, it often falls to lawyers to give advice to parties regarding the meaning of particular terms of such instruments. Inferences ought not be drawn from the seeking of such advice.
