Testimonial privilege: Van Der Heijden v The Netherlands

In the case of Van Der Hejden v The Netherlands' the European Court of Human Rights grappled with the scope of testimonial privilege and specifically whether a de facto partner of an accused should be accorded
a privilege not to testify against her partner. The law in the Netherlands provided a testimonial privilege for 'spouses' and for 'registered partners', but not for those in de facto relationships.
