Use of the common passage leading to the garage

I have a 2 year lease rent agreement of the first floor of a two storied house with my landlord who also has a long lease rentee at the ground floor.

The ingress and egress of my hired garage is a common space and is often blocked by the long lease rentee of the ground floor and they are demanding that I should put their car out and in whenever I need my car .

Is it a normal practice at  FD block of salt lake kolkata and what are the relevant prevalent  rules .
