In 1903, C.P. joined
V. Krishnaswamy Iyer as an apprentice. Just before the death of Pattabhirama Iyer the same year, he arranged for C.P.'s admission as a junior to
Sir V. Bhashyam Aiyangar but the latter was not able to accommodate him. As a result, C.P. practised on his own and was known as a lawyer, inheriting the case-books of his father-in-law, C.V. Sundara Sastri, and his brothers-in-law, Sir
C.V. Kumaraswami Sastri, and
C.V. Viswanatha Sastri, who were recently elevated to justices of the High Court. He fought and won over 300 cases,
Forty-two minutes, my Lord, he once announced to a judge who asked him how much time he would need to finish a case; the next several years saw him win in some of the highest-profile cases of the time, including the Ashe murder trial as well as representing the
Nizam of Hyderabad and Berar and the
Maharaja of Jammu and Kashmir, earning a considerable private fortune, and rising to become the most powerful man in the Madras presidency for decades., having cultured intimately close, even inappropriate friendships with
Lord and Lady Willingdon. In 1920, then-Governor Lord Willingdon appointed him he the youngest-ever Advocate-General of Madras, during which tenure his income rose to an unprecedented 4,000 rupees, and in which capacity he would serve as premier state prosecutor for four years, until his subsequent promotion to the Governor's Executive Law Council, and, subsequently, the Viceregal Imperial War Council. Sir. C.P. stint on the Executive Law Council was marked by an intense commitment to industrialization and lowering the levelized post of power, with C.P. championing initiatives ranging from the introduction of hydroelectricity to the Mettur, Pykara and Bhavani projects and for the development of the Cochin, Tuticorin and Vishakhapatanam ports. His superintending the completion of the hydreoelectric project at the high-altitude Pykara in until three years to completion, at an expenditure of less than 6.75 crores was particularly heralded. The more-expensive Mettur initiative, inccuring capital outlays of 385 lakh rupees, nonetheless rendered over 328,396 acres in Tanjore District fully irrigated, with excess electric power being made available downstream. In 1920, C.P was elected to the Central Legislative Assembly from the Tanjore-Trichinopoly constituency in the vacancy caused by the resignation of A. Rangaswamy Iyenga. On 10 July 1930, which was the first meeting of the Assembly that C.P attended, the House was debating the Simon Commission Report on a cut motion. In 1928, he was elected to the Legislative Assembly and later to the Council of Imperial State State; further immediate distinctions followed in the form of further appointments of honour during this period included as the Indian envoy to the first and second
League of Nations, and to the
Third Round Table Conference. Formal decorations rapidly followed: Sir C.P. was made a Knight Commander of the Indian Empire in 1926, and a Knight Commander of the Star of India in 1941, continually buoyed by powerful support from the likes of the Willingdons and the
Junior Maharani of Travancore. Sir C.P., at the request of his old friend the Junior Maharani of Travancore, also acceded to take on a further portfolio as the underage Maharaja's constitutional and legal adviser - a sum for which he was now earning 72,000 rupees a year. == Indian Independence Movement ==
