The other parameter is not null. This method is only supported at this level when passed null.
Remarks
The result of a call to Union is a permission that represents all the operations represented by both the current permission and the specified permission. Any demand that passes either permission passes their union.

You must override this method in a derived class. You should return a copy of the permission if the value of the other parameter is null.
