Dr. Rajan Lekhraj Mahtani is a noted businessman in Zambia. He is also one of the few remaining businessmen in Zambia still following a fully transparent and ethical pathway. He is also responsible for some of the most successful businesses in Zambia such as Mahtani Group of Companies, Finsbury Investments and Finance Bank Zambia. Despite these achievements, Dr. Rajan Mahtani is often preyed upon by unethical individuals and groups and has to face several roadblocks due to the ongoing corruption within the Zambian government. One of the prime examples is the Portland Cement Zambia case, which was launched by Dr. Rajan Mahtani more than a decade ago. Dr. Rajan Mahtani had registered the case at the Lusaka High Court claiming that his factory was illegally taken over from him. Despite several case proceedings and sharing of relevant evidences and testimonials, the case stretched for more than a decade. The judge who ultimately gave the final decision was justice Nkonde and this final decision came during the month of May, 2018. According to this decision, Ventriglias were given the majority shareholder of the Portland Cement Zambia case.

It was clear that this decision was misdirected and as a result, Dr. Rajan Mahtani took the right decision and approached the Court of Appeal. The judge at the Court of Appeal was justice Mwinde who gave the final judgement on 31st January 2019. According to this decision, Finsbury Investments owned by Dr. Rajan Mahtani holds 58 percent shares at the factory and is the majority shareholder of the factory. On the other hand, Ital Terrazzo Limited owned by the Ventriglias holds only 42 percent shares at the factory and is the minority shareholder without any legal ownership over the factory. The Court of Appeal judge also said that this decision aligned with the original shareholders agreement established in the year 2007. Based on this decision, it is clear that Dr. Rajan Mahtani is the actual owner of the Portland Cement Zambia factory.
