(ii) Ex.P7-disability certificate shows that the appellant has sustained locomotor disability which means disability of the bones, joints or muscles leading to substantial restriction of the movement of the limbs or any form of cerebral palsy. Thus, it is evident that the appellant has completely lost his earning capacity. Being a Mechanical Engineer, locomotor disability will highly affect his avocation and therefore, we are of the view that multiplier method should be adopted for computing the disability compensation. The age of the appellant was 27 years at the time of accident. As per the judgment in Sarla Verma v. Delhi Transport Corporation, reported in 2009 (2) TN MAC 1 (SC), the appropriate multiplier is 17. Though the appellant marked Ex.P11-pay slip and Ex.P12-salary certificate to substantiate his monthly income at Rs.23,800/-, in the absence of examination of its authors, the Tribunal relying upon the judgment in Nithya and others vs. The Tamil Nadu Coop Milk Producers Federation Ltd., Chennai and others reported in CDJ 2018 MHC 1565, fixed the monthly income of the deceased at Rs. 12,000/-. We also confirm the said fixation of monthly income. Applying multiplier method, the disability compensation is computed as follows:Rs.12,000 x 12 x 17 x 57/100 = Rs.13,95,360/-
