As i stated in several posts before this here, "You borrow to finance an appropriation that has been passed", happens at the budget making stage where parliament discusses expenditure for the next financial year including public participation. After that parliament will be needed only when a supplementary budget is needed or funds, borrowed or from revenue collection have been used inappropriately(Oversight).
What you said is that parliament must approve every act of borrowing by treasury even after budget is passed and that public participation must be conducted as required by law. Well that is a claim that even your own evidence does not support neither does it claim what you are claiming.
This part here.
"The Government may, under agreements or other written instruments, borrow or obtain credit for sums in currencies other than Kenya currency from any person or government, upon such terms and conditions as to interest, repayment or otherwise and in such manner as the Minister responsible for finance may think fit, and may, subject to section 3, expend moneys or purchase goods or services on credit in accordance with those agreements or instruments"
section three mentions approved expenses by parliament, not approval to borrow by treasury.
