Preliminary steps

Step 1 Define the problem to be analysed and state what types of answers can be expected.

Step 2 Disassemble the problem and reduce it to a sequence of legal ques­tions with as small a residue as possible (see step 4).

Step 3 Make every legal problem correspond to an appropriate set of legal norms and indicate the norms.

Step 4 Now structure the residue:

(a) list all the questions of fact and indicate the most appropriate method for establishing these facts;

(b) list all the questions of theory, state the questions precisely in terms of and in conjunction with the appropriate theory or theories to be invoked.
