The case of Portland Cement Zambia is a good example of patience and perseverance for Dr. Rajan Mahtani. The factory was under the leadership of Dr. Rajan Mahtani when it was unethically captured from him. This prompted Dr. Mahtani to take the case to Lusaka High Court. After sharing numerous evidences and testimonials, it was expected that the judge will provide an easy judgement. However, despite dragging the case for more than a decade no respite was given to Dr. Mahtani and the final decision was given against his claim. To counter this, the Court of Appeal was approached which is the highest civilian and legal system in Zambia. The judge at the Court of Appeal was justice Mwinde and the final decision was announced on 31st January 2019. As per this decision, Dr. Mahtani was found to be majority shareholder as well as legal owner of the Portland Cement Zambia factory with 58 percent shares.
