What is the test for unreasonable delay in applying for Charter of Human Rights?

When the trial judge here dealt with the appellant’s Charter application, he addressed the issue of unreasonable delay and initially found that the time from the appellant’s first Court appearance to the date of the application did raise an issue of unreasonable delay being fifteen and a half months, and therefore, he decided that he would look at the factors set out in the leading case of R v. Morin 1992 CanLII 89 (SCC), [1992] 71 CCC (3rd) 1, to determine if the application should succeed.
