Key legal question
How must the family income under Art. 22(2) LEE be calculated by reference to Art. 18 LEE, especially whether Art. 18(2) is also included in the triple calculation.
Extracted holding
The reference in Art. 22(2) LEE to Art. 18 LEE also covers Art. 18(2). The authority must first triple the income amount from Art. 18(1), then add any amount provided for in Art. 18(2); it may not simply triple the amounts in Art. 18(1) and (2) together.
Extracted reasoning
To reflect legislative intent, the calculation structure is cumulative rather than purely multiplicative: the amount under Art. 18(1) is tripled, and the supplementary amount under Art. 18(2) is added afterward if applicable.
