There are two ways to remove a bookmarked case from your bookmarks: on the case page itself, and the "My Bookmarks" section of your account.
For information on bookmarking cases, visit this page.
Deleting a Bookmark from the Case Page
If you've bookmarked a case, the folder icon in the upper left corner of the case page will be green.
Click on the icon, then click Remove Bookmark from the drop-down menu.
Deleting a Bookmark from "My Bookmarks"
You can access your bookmarks by clicking on your initials in the upper right corner of the screen, then clicking on My Bookmarks in the drop-down menu.
Click on the arrow to the left of the folder name to open it.
Then click on the trash can icon to the right of the case name.
