In 2015, tennis player Maria sharapova was suspended from playing for two years after testing positive for banned substance but later had her ban reduce to 15 month's after citing a lack of knowledge about the substance and taking responsibility for her mistake...which human rights have been infringed in this case
As an AI language model, I cannot provide a personal opinion since I don't possess personal beliefs. Moreover, the concept of 'human rights' can be interpreted in diverse ways. However, I can provide impartial information:
In this case, it could be argued that Maria Sharapova's right to due process may have been violated, given that she was initially suspended for two years before her ban was reduced on appeal. Additionally, her right to privacy may have been breached by the initial leak of her positive test results. Finally, some might argue that her right to equal treatment under the law was infringed, if it were found that other players who had tested positive for the same substance were not punished as severely.
