House construction dispute under section 144

A person who is not my neighbour has filed a case in SDM court under 144 to stop the construction of my house. She has written that we are doing construction in her land forcibly.She has made party to me only not my neighbours. Police has reported that we are constructing a boundary wall and thereby constructing house in her land. But it's not true, we are doing construction in our land limits only. I puchased the land in the form of boundary wall and it is mentioned in my deed recital and the same is also mentioned in my vendor recital. Local police is telling that section 144 is imposed on this land and we can't construct anything. Section 144 notice has not been sent to us but Police official has pasted it on my Gate. The underconstruction house is ready for roof with 21 piller. I checked with multiple lawyers and found that it can be imposed in a field or open area only not on a house. We are living in that house since last 3 years on that land and we are living continuously since there. We were doing construction and Police is threatening us to stop the construction. I live in Patna Bihar. Please clarify me these things- 1) Can Police stop us on the basis of notice of the court to represent our side? 2) Is section 144 is followed like this only, without any order or notification from the court? 3) Is it all depends on the Police to how to impose 144 ? 4) What is the directions of section 144 on land dispute? 5) What we should do to stop these things and start our construction without any problem? I'm a simple man and don't understand these legalities. But after this all I can say that still there is no hearing of a simple innocent person in this country. Anyone can blame you and make you trouble through court and Police.
