3. Why was the EC’s measure found not to be based on a risk assessment, under Article 5.1 of the SPS Agreement?

May a Member base its SPS measure on a risk assessment reflecting a minority scientific opinion? For a measure to be ‘based on’ a risk assessment, is it sufficient to show that the risk assessment was considered when the measure was adopted?
