A grandmother knew someone that was a soldier in World War One and the soldier told her all of his stories about life on the front lines. The grandmother retold those stories to her grandchildren. Is the grandmother a primary or secondary source?

secondary

Explanation:

Think of the grandmother as being something like a newspaper. She is told some stories about WWI and she records them. Maybe she edits the order in which they were told her, but if she has a good memory, she doesn't change the facts of the story.

That places her in the same category as a newspaper. That's a secondary source.  It interviews people to get their stories, but the reporter doesn't repeat the events. He /  she merely writes what she has been told up and an editor sees that it is printed. Same with grandmother. She just reports what was told her. She did not re enact the experience.

`stare decisis is a legal doctrine that obligates courts to follow historical cases when making a ruling on a similar current or future case. stare decisis ensures that cases with identical facts be approached in the same way, unless overruled by the same court or a higher court such as the us supreme court. simply put, it binds courts to follow legal precedents set by previous decisions.

stare decisis is a latin term meaning "to stand by that which is decided".
