XIII. Continental Chemical Corporation (CCC) filed a complaint for a sum of money against Barstow Trading Corporation (BTC) for the latter's failure to pay for its purchases of industrial chemicals. In its answer, BTC contended that it refused to pay because CCC misrepresented that the products it sold belonged to a new line, when in fact they were identical with CCC's existing products. To substantiate its defense, BTC filed a motion to compel CCC to give a detailed list of the products' ingredients and chemical components, relying on the right to avail of the modes of discovery allowed under Rule 27. CCC objected, invoking confidentiality of the information sought by BTC. Resolve BTC's motion with reasons.
