For example, in R. v M., Justice Lamer of the Supreme Court of Canada wrote, at ¶69:"If an offender has committed a severe enough offence to warrant a life sentence, the offender will, ceteris paribus, represent a greater threat to society than an offender who received a non-life sentence."Or, in Vines v General Outdoor Adventures, this remark by Justice Land of the United States Court of Appeals:"In a release words of general import, followed or preceded by words relating to specific claims, are, ceteris paribus, limited to the specific claims."REFERENCES:R. v.
