The document discusses tax havens, GAAR (General Anti-Avoidance Rules), and their implications. GAAR aims to minimize tax avoidance by empowering officials to deny tax benefits to transactions without commercial substance that are solely aimed at achieving tax benefits. Some concerns discussed include GAAR being too sweeping, difficulties distinguishing avoidance from mitigation, and need for checks on arbitrary application. Investors were uncomfortable with GAAR's original form due to these issues.
