Amid the case relating to the former Indian billionaire’s huge Kingfisher airlines debt, Mallya was arrested and bailed in London recently.
The Indian government is seeking the 61-year-old’s extradition, but Force India driver Perez insisted in Russia: “The team is in a good situation.
“Vijay is probably glad about the proceedings — now there is some certainty and he believes that everything will go in his favour,” the Mexican added.
“Vijay is optimistic and we look forward to having him back.”
Hunted by Indian legal authorities over unpaid loans tied to his non-operational Kingfisher Airlines, Mallya was arrested in London last week and appeared at Westminster Magistrates Court for an extradition hearing before being granted bail.
A source close to Mallya told Reuters at the time that the 61-year-old had attended a police station voluntarily in an arranged visit and the arrest was a technical procedure.
India has asked Britain to extradite Mallya to face trial after the liquor and aviation tycoon fled there in March last year.
Banks are seeking to recover about $1.4 billion that the Indian authorities say Kingfisher owes.
Mallya has repeatedly dismissed the charges against him and defended himself in messages on Twitter and rare interviews.Mallya has a base in London and a lavish country home bought from Anthony Hamilton, the father of triple F1 world champion Lewis Hamilton.
