Central Sales Tax amendment clarifies Section 10A's cross reference to subsection 4 of Section 8, correcting the citation. Amendment clarifies a cross reference in Section 10A by substituting the reference to 'clause (a) of sub section (4) of section 8' with 'sub section (4) of section 8,' thereby changing the textual link between Section 10A and the relevant provision of Section 8 for interpretation under the Central Sales Tax regime.
