When they 'MUST' do something, under the HTA, the word 'shall' is used in the statute.
Where is the significance of 'shall' specified? Gonna guess it's in some other, less specific document relating to how to read laws in general?
You definitely seem to know what you're talking about with legal stuff, so maybe you can enlighten me here: How should the following hypothetical clauses be interpreted?
1. The officer may jump and jive.
2. The officer shall jump and jive.
3. The officer may jump or jive.
4. The officer shall jump or jive.
Are clause 1 and clause 2 different? If 'shall' means what you suggest, then is the interpretation that clause 2 requires that they both jump and jive in the specified order, but clause 1 would permit them to either jump without then proceeding to jive or to simply proceed straight to jiving with no jumping occuring?
If that's the case, does that make clauses 1 and 3 identical? Or does clause 3 preclude doing both, but permit them the option of doing one or the other on it's own?
Could the officer, in any if these cases, jive first and jump second?
How would a clause permitting an optional sequence of actions be written, wherein the sequence is optional in it's entirety but, if performed must be performed completely and in order? E.g., if I wanted a clause the allowed the officer the option of jumping and then proceeding to jive (e.g., the officer may choose to do nothing or may choose to jump and then jive, he may not choose to merely jump or merely jive), how would that be worded?
