The proposed future 
collider provides sufficient energies to produce the Standard Model Higgs Boson (h) through 
and Z-Boson fusion in charged and neutral current modes, respectively and to measure its properties. We take this opportunity to investigate the prospect of measuring the CP properties of h through 
, where 
decays to a charged pion 
and a neutral pion 
in association with neutrino (anti-neutrino). An interesting CP sensitive angular observable 
between the two 
-leptons decay plane in the 
centre of mass frame is proposed and investigated in this work. For fixed electron energy of 150 GeV along with 7 (50) TeV of proton energy, the CP phase can be measured approximately to 
(
) at integrated luminosity of 1 ab
for −80% polarised electron at 95% confidence level.
