Is the Fence part of the course?
Seems to me the key question is whether the fence is part of the golf course. If it is, and it is a boundry, it should be white staked, therefore no relief. See #15 at Loch March in the Rules forum.

If the fence is not part of the golf course, again no relief.
If it is part of the course and is not marked as out of bounds I believe it would be an immovable obstruction and your FC would be entitled to relief under Rule 24-2 b i.
Just my own opinion, Gary will have the right answer!
