How did suspended JDS leader Revanna fly to Germany without a visa note?

Under a reciprocal agreement signed in 2011, holders of Indian diplomatic passports are not required to obtain a visa for visits to Germany, as long as their stay does not exceed 90 days.  India has similar agreements with countries such as Italy, France, Afghanistan, Iran, among 90 others. Under these agreements, not only diplomatic passport holders but also those with service and official passports can benefit from operational visa exemptions.
