From the resolution of contentious issues regarding distribution of legislative powers by the courts, Principle of Federal Supremacy and Harmonious Construction have emerged. Explain.
In short
When legislative entries overlap, courts first read them harmoniously so each operates in its own field, and only if conflict is irreconcilable does the Union law prevail under Articles 246(1) and 254. Mineral Area Development Authority v. SAIL (2024) reconciled the Union's mining entry with the states' power to tax mineral rights.

Textual basis
Article 246(1) gives Parliament power over the Union List "notwithstanding" clauses (2) and (3), so in an irreconcilable overlap the Union entry prevails.
Concurrent repugnancy
Under Article 254(1) a central law prevails over a conflicting state law, judged by the M. Karunanidhi (1979) tests, though Article 254(2) saves a state law that receives the President's assent.
Applied
In Adhiyaman Educational Institute (1995), Tamil Nadu's rules on technical education gave way to the AICTE Act, made under the Union entry on coordination and standards.
Reconcile first
Courts identify a law's pith and substance and read overlapping entries so that each operates in its own field, because the lists are meant to coexist and no entry should be rendered meaningless.
Classic illustration
The Federal Court's motor spirit case (1939) upheld both the federal excise on manufacture and the provincial tax on sale.
Reading together
Gujarat University v. Mudholkar (1963) let a state set the medium of instruction only so far as the Union's power over standards was unaffected.
