Administrative Bureaucracy: Explain 'Ultra Vires' to Me

Bhai, textbook mein likha hai ki Ultra Vires kya hai, lekin uska matlab aisa hai jaise koi ghar ka chokra apne aadmi ko 'yeh kehne laga ki yeh main ghar ka malik hoon'. Ab main samajhna chahta hoon. Kya yeh kaafi hai? Kya yeh bhi sahi hai? Aur agar ultra vicious hota, to phir kya hota? Please batao, meri judiciary life ko sambhalne mein madad karo!

Example ya real-life scenario batao jisse ham ultra vires ko samajh saken.
