The burden of proving discharge rests upon the party claiming it, and legal precedents can be relied upon to modify interest rates based on economic factors.

JUDGMENT

1. The Appeal, under Sec. 96 of the Code of the Civil Procedure, is filed by the appellants/defendants challenging the decree and Judgment dtd. 31/12/2009 in O.S.No.771 of 2008 passed by the learned III Additional Senior Civil Judge (Fast Track Court), Guntur (for short, 'trial court'). Respondent is the plaintiff in the suit, who filed the suit in O.S.No.771 of 2008 seeking recovery of Rs.9, 51, 242.00 with interest and costs from the defendants towards Khata dealings between them.

2. The parties will hereinafter be referred to as arrayed before the trial Court.

3. The facts leading to the present Appeal, in a nutshell, are as under:

(a) The plaintiff firm has been involved in the cotton trade, regularly supplying cotton to the 1st defendant's firm on a credit basis. The 1st defendant firm engages in substantial business activities with significant turnovers. All the partners in both firms actively participate in the business transactions. The 1st defendant firm opened a Khata with the plaintiff firm, they purchased cotton on credit basis, with two separate bills: Bill No.7, dt.8/12/2006 amounting to Rs.5, 93, 433.00 and bill No.8, dt.13/2/2007 amounting to Rs.5, 36, 628.00. Both parties agreed that these amounts would carry the interest rate @ 24% per annum accruing the bills date until the date of payment. The Khata of the 1st defendant firm was entered in the plaintiff firm's account books, which are maintained in the regular course of their business. After opening the Khata of 1st defendant firm, it made two payments, one of Rs.3, 00, 000.00 on 18/1/2007 and another of Rs.2, 00, 000.00 on 10/5/2007 through cheque payment.

(b) In 2007, one of the partners in the 1st defendant firm, Chittiprolu Suryanarayana, died intestate in 2007, leaving behind his wife Nagabhayamma and his sons Jagan Mohan Rao and Srinivasa Rao, as his legal heirs. After his death, the 1st defendant firm continued to operate with the remaining partners, specifically defendants 3 to 7, and they were responsible for the 1st defendant's firm's debt. The plaintiff made repeated attempts to collect the outstanding debt from the defendants, but the defendants postponed on one pretext or another. Additionally, the 1st defendant borrowed Rs.3, 75, 000.00 from the plaintiff on 19/8/2006 by way of hand loan, agreeing to repay the same with interest @ 18% p.a., and to that effect a receipt dt.19/8/2006 was issued by one of the partners of the 1st defendant's firm, Jagan Mohan Rao to confirm the loan amount. Despite this, the defendants only made a part payment of Rs.1, 00, 000.00 on 23/1/2007 towards settling the personal loan debt.

4. Defendants 3 to 7 have adopted the 2nd defendant's written statement, in which, they asserted that 1st defendant is a registered firm. Initially, the firm was formed by partners, Late Chittiprolu Suryanarayana and his sons Late Jagan Mohan Rao and Srinivasa Rao along with the 2nd defendant for the benefit of their joint family. After the demise of Chittiprolu Suryanarayana, the responsibility for all business and financial transactions fell on his elder son, C.Jagan Mohan Rao. Subsequently, he died. During their lifetimes, the entire amount owed as per the Khata agreement was paid by them to the plaintiff, albeit at a higher interest rate. Upon Jagan Mohan Rao's passing, the plaintiff visited the defendants' residence and acknowledged the receipt of the outstanding amount. At that time, there was an understanding that the matter had been settled through negotiations between the elders. The plaintiff then collected substantial sums from the 2nd defendant, indicating that he would close the Khata and provide a receipt for a full and final settlement. However, the plaintiff failed to issue the promised receipt and continued to postpone doing so. The defendants argue that the interest claimed by the plaintiff is exorbitant and unfair.

5. Based on the above pleadings, the trial Court framed the following issues:
