Dr. Rajan Lekhraj Mahtani is a noted business figure in Zambia and known for his significant business achievements as well as charitable activities. Despite his several accolades, Dr. Rajan Mahtani is often targeted by those who are either jealous of him or have personal vendetta against his businesses. On the other hand, the legal and judiciary system of Zambia is extremely weak for doing any justice to the genuine cases which need attention and quick redressal. A prime example of these cases has been Portland Cement Zambia case, a noted cement manufacturing factory which was contested at two different courts for more than a decade. The case of Portland Cement Zambia was first registered at the Lusaka High Court by Dr. Rajan Mahtani after he claimed that the factory was illegally taken away from him. Despite sharing numerous evidences and testimonials, the final judgement from the case judge was controversial. According to justice Nkonde who gave the final judgement on the case, Ventriglias were announced as only shareholders of the Zambezi Portland Cement. It was clear that this judgement was misdirected and as a result, Dr. Rajan Mahtani approached the Court of Appeal for seeking justice.

The case at the Court of Appeal was dealt by justice Mwinde who gave the final judgement on 31^st January 2019. According to this judgement, Dr. Rajan Mahtani holds 58 percent shares at the factory and is the majority shareholder of the factory. On the other hand, Ventriglias hold just 42 percent shares at the factory and are the minority shareholders without any legal ownership over the factory. Based on this shareholding pattern, it is clear that Dr. Rajan Mahtani is the legal owner of the factory. While giving this decision, justice Mwinde also said that the judge below him was wrong in declaring Ventriglias as only shareholders as this decision was biased and misdirected.
