World number five Rafael Nadal refused to reveal any further details on the lawsuit he is pursuing against former French sports minister Roselyne Bachelot, who accused him of doping.
Bachelot alleged the 14-time grand-slam champion missed the 2012 ATP Tour season to hide the use of performance-enhancing drugs.
Nadal, who has since pursued legal action, stated that tendinitis and illness were the reasons for his time away from court.
And the 29-year-old was tight-lipped when asked about the matter as he prepares for next week's Madrid Open.
"We are now in a legal process so I have said many times I won't be speaking about it right now. I said everything I had to say at Indian Wells when she spoke about that," Nadal told reporters.
"I said what we were going to do and we have done it. We have done it when we have everything ready for that in order to file the complaint. We are now under law's hands so I don't have anything more to say.
"I trust the law. I had to do that because there is a time when I had to say that's it. It's enough. It's time I respected the process as we have done everything we had to do, so just wait."
Nadal, though, was happy to discuss his chances at the Madrid Open.
A four-time champion in Madrid, Nadal heads to the Spanish capital following back-to-back wins in Barcelona and Monte Carlo as he gears up for next month's French Open.
"I am feeling well as I have said I think I have been feeling well all the season but there weren't good results at the beginning," he added.
"I am confident of keeping going and working in order to keep these weeks' level. Madrid is a special tournament, not just because it's a Master 1000 and we play at home. I enjoy playing at home in the last two weeks in Barcelona and Madrid. They are two awesome weeks on the season.
"I want to enjoy and I want to be ready for this. I was last week and I hope to be the same here."
