No, it relates to proposed subsection 269(1.1) I know the brackets in subsection 269(1) are confusing but it's just a continuation of proposed subsection 269(1.1). It's a six-month limitation period for prosecutions other than the ones that are specified, in other words, the NDA and Crimes Against Humanity and War Crimes Act.
