Should this be a crime?

Stuff reports:

A brother and sister who met as young adults have been sentenced for incest as they co-parent their child in Christchurch.

The sister has been put on community detention that will keep her at home at night caring for her daughter – a healthy baby – and she must do a year of intensive supervision.

Her older brother’s sentencing was put off at the Christchurch District Court sentencing today because his probation report had not been done.

Judge David Saunders told the brother that he must not go within 100m of flat where his sister is living unless he has prior approval of the Community Probation service.

The sister has the child for five days a week, and the brother has it for the other two days. He will be sentenced on December 2, on charges of incest, wilful damage, and a breach of a community work sentence.

Judge Saunders told the sister at her sentencing that it was not the more common incest situation where an older man had taken advantage of a daughter.

In this case they were siblings and there was only a small disparity in the ages.

While incredibly yucky, they are both consenting adults. I find their decision abhorrent, but I don’t think my moral judgement should have the force of law on them.
