Schmeiser claimed that because the 1997 plants grew from seed that was blown into his field from neighboring fields, that he owned the harvest and was entitled to do with it whatever he wished, including saving the seeds from the 1997 harvest and planting them in 1998. The case went to the Supreme Court which took the case and held for Monsanto by a 5‑4 vote in late May 2004.[22] The case is widely cited or referenced by the anti-GM community in the context of a fear of a company claiming ownership of a farmer's crop based on the inadvertent presence of GM pollen grain or seed.[23][24] "The court record shows, however, that it was not just a few seeds from a passing truck, but that Mr Schmeiser was growing a crop of 95–98% pure Roundup Ready plants, a commercial level of purity far higher than one would expect from inadvertent or accidental presence. The judge could not account for how a few wayward seeds or pollen grains could come to dominate hundreds of acres without Mr Schmeiser's active participation, saying '. . .none of the suggested sources could reasonably explain the concentration or extent of Roundup Ready canola of a commercial quality evident from the results of tests on Schmeiser's crop'" – in other words, the original presence of Monsanto seed on his land in 1997 was indeed inadvertent, but the crop in 1998 was entirely purposeful.[25]
