>There is an international trend to move from explicit consent (opt-in) to presumed consent (opt-out) policies for deceased organ retrieval: Chile (2010), Finland (2010), Greece (2013), Uruguay (2013), Wales (2015), Colombia (2016), Iceland (2019), the Netherlands (2020), England (2020), Scotland (2021), and the province of Nova Scotia in Canada (2021) have implemented opt-out policies. Switzerland is presently considering it, and Australia, Denmark, Germany, Israel, Romania, and several states in the USA had been discussing this as well.[0]
As far as I'm aware, none of the listed western countries (except Chile, whose status as a "western" country is dubious) allow the use of organs for 'scientific experimentation' without consent. Additionally many of the listed countries (Finland, Greece, ...) require attempts to ascertain consent for those organ donations, which means asking family members of the deceased.
Examples?
