Step 1: What Section 37 allows.
Appeals lie from orders granting or refusing Section 9 interim measures, accepting or rejecting jurisdiction, and granting interim measures under Section 17.
Step 2: What's not covered.
Section 37 does NOT permit an appeal against refusal to grant interim measures under Section 17. Only \textit{granting} such measures is appealable.
Step 3: Conclusion.
Hence, refusal under Section 17 is not appealable.
