Unfortunately I'm finding it a bit difficult to read the attachment but I would make the following remarks based on my understanding:
There are usually compensatory fails for marks under 40 (eg optional units), but there can be units in vocational degrees which are essential to be passed in order to progress to the next level/graduate.
So it may depend on whether land law is a compulsory module etc.
The only way to clarify would be to see your administrator asap
Good luck!
