  We propose a spectropolarimeter a covering wavelength range of 3200--7000
{\AA} [3200{\AA} chosen as lower limit to go to the atmospheric cut-off. It's
``needed" for some Serkowski curves and would make the instrument even more
unique] for a 2-4~m class telescope. In this article, we discuss the science
cases which will be covered with this proposed instrument. The technical
requirements and analysis plan for each science case is also discussed. This
spectropolarimeter targeting exciting galactic and extra-galactic research,
will be unique instrument on a 2-4~m facilities.
