Arbitrary dismissal and calculation of the compensation

I believe I have a strong case of arbitrary dismissal.

I understand from article 115 of Labor Law that if this is the case my employer is bound to compensate me for a maximum of 3 months total wages.

My questions are:

1) By using the word maximum does that mean they can pay less than 3 months?

2) My contracted monthly pay is split into two parts: basic and allowance. Could they argue I am only entitled to 3 months basic pay and not the total amount?
