I'm not gonna look at the link because it's a blog, but the language cited in this excerpt shows that a 15-year-old could not get sterilized without parental consent. The Oregon law cited specifically says consent has to be "given by an individual competent to make such a decision". That's a pretty straightforward legal term meaning someone who is over 18 and who is not mentally unsound. I'll immediately retract my analysis (and be completely horrified) the first time I hear of an actual rather than a hypothetical 15 year old being sterilized.
LonelyCon, I provided a link to Catholic Online as well as my blog. Before it says “individual competent to make such a decision,” it says ““(a) Based upon a full understanding of the nature and consequences of sterilization pursuant to information requirements set forth in ORS 436.225(1);”
Who makes the decision that there is a full understanding and what 15 year old can have a “full” understanding of such an important life event? It won’t be the parent.
